Please tell me if this is correct?
I thought F stops were depth not light

Yes, you are mistaken. As AstroNikon pointed out above, the aperture controls the amount of light reaching the sensor and is PART (but ONLY part) of the depth of field equation.

F-Stops *IS* Depth of Field AND the amount Light though not How long for that amount of light (which is shutter speed).

The Aperture size / opening size may allow little of alot of light in per the time (shutter speed).

The exposure triangle and the basics for selecting Aperture-Shutter Speed and ISO are in the first few chapters of photography books. They all affect exposure. It seems we jumped over a very important step. Hopefully the above posts clear that up.

Ok,
without trying to understand everything in one day. I am trying to find the best settings for my shoots, until I can buy and set up strobes.
It is obvious, that with the proper light intensity (strobes), I could shoot at high S values and low ISO, then, we would all be on the same page, since all you guys are using strobes. Until then, I have to make do with what I have, and find the best possible setting (ISO, A, S,) now, so as to continue shooting, whilst i'm learning.

I no longer stand 9 feet back, I am trying to get as close to my subject as possible with the 50mm. All my lights are crowded as close to the subject as possible. If the bag is reflective, I will change the position of the lights, still keeping them as close as possible, so as to reduce the hot spots or reflections.
Last night I took Dave's advice and increased ISO and increased S to 1/60. I was expecting huge noise and got very little.
Is there any advice you can offer on the A value if a bag is facing me? In other words if a bag is facing me there can be no depth to it? Should I still shoot it at higher F values (f9~f11). Does the FVALUE affect right to left? Or only depth? Should i focus on the center of the bag?

The Aperture size / opening size may allow little of alot of light in per the time (shutter speed).

So, since I am deficient in light (no strobes) I should allow more light in the aperture and use f/2? which allows more light to enter? But f2 has no depth to it, so most of the bag will have bokeh?
If my logic is correct, I need to increase A until the whole bag is sharp (no bokeh) (probably f7~f11) depending on the position of the bag, and decrease S to lower the light.
So Dave told me to increase ISO (which increases the light) but to increase S which lowers the light.
Just got to find a happy middle ground to all this, until I have the strobes.

if you increase the time your Shutter stays open it will allow more (time -wise) light into the sensor. using a larger opening Aperture *will* affect your Depth of Field.

Thus you select the Aperture that you *need*. then that stays fixed.
Then you have Shutter and ISO to help compensate for lack of light.

at some point when Aperture, Shutter and ISO are maxxed out per the settings requirement w/o affecting the image one needs to add light.

you can also pull out shadows in post processing to compensate for not enough light, which at some point introduces noise.

Here is my current set up. I just realized i could place the LED panels inside the tent, so they are very close to the bags. This is going to change the the whole S value, I can now probably increase to 1/100 at least.

..I just learned that the F stops let in more or less light..

That right there illustrates why we are so frustrated at trying to get you up to speed. You're still in neutral. How can you gain any traction that way?

Please tell me if this is correct?

Incorrect, because it's both at the same time.

You could try using your meter. If you are shooting in "M" manual, the meter will show you where a good exposure is. Further fiddling with exposure at your stage of understanding is not recommended.

Guys please help me here with this shot.
I placed the LED panels inside the tent. This enabled me to go up to s/250. This was previously impossible for me.
The coach hand tag is too bright.

I have 3 options :
1. diminish the intensity of the LED panels.
2. decrease S
3. decrease ISO

Should I try a little of all 3 above?

No more advice from me until:
1. You stop calling them "S-Values" or anything other than Shutter Speed.

2. You stop calling them "F-Values" or anything other than Aperture.

3. You COMPLETELY (from the first word to the last word) read AND UNDERSTAND This Tutorial.

Everyone is trying to help you but you keep going around and around and around in circles because you don't understand the rudimentary basics of exposure and won't take the time to understand them. You're just randomly throwing things in different directions hoping something will stick, and it's not going to until you understand the basics of exposure. You have got to stop throwing things around and start trying to understand the basics.

Meter? Where? is it a device i have to buy? Or is it in my camera already? Is it called an exposure meter?

If you increase light
1 - you do NOT want to change Aperture as you need the DOF.
2/3 - thus you can use a (a) LOWER ISO and/or (b) use a faster shutter speed.
(a) decreases the sensors sensitivity to light
(b) faster shutter decreases the amount of light coming in the aperture.
"and/or" is important as you can use one, the other or BOTH.

use your meter in the viewfinder or LCD to see where it balances out.
