The basics of exposure don't care what brand name is on the camera. Put the camera on a tripod. Set the ISO to 100. Set the aperture to something in the middle (e.g. f/8). Set the shutter speed to whatever it takes to create a balanced exposure.
As for the yellow... this is a white balance problem caused by your lighting.
When you do product photography (especially when representing products that come in colors) you MUST MUST MUST use a proper color-managed workflow. This "starts" with the camera, but includes your computer and, if you get printing done (it's not just for on-screen catalogs) then the printers have to be calibrated. Even if you send out to a printing service, the printers STILL need to be calibrated (better printing services provide this information -- even Costco (of all places) will send you the color calibration profile of the specific printers located in the labs in each store.)
You can use the white balance settings in the camera IF you are shooting JPEGs. If you shoot RAWs the white balance is ignored (you always fix white balance in post processing when you shoot in RAW.)
To get accurate white balance (and for product photography you really NEED accurate white balance) you need to buy a true neutral "gray" card. I use a collapsable gray card for shoots, but if I were doing product photography I might pick up a DataColor SpyderCube (it's a self-standing gray card you can set inside your light box.) One of the interesting things about this "cube" device is that instead of just calibrating the neutral gray at the midtones, it also lets you set the white point and black point. It has a black spot on the underside in the shadows and white highlights on the top where it'll pick up highlights. This gives you a little more control over your image processing then you'd get with just a straight gray card.
If you shoot in JPEG, take a close-up photo of the gray card so that it mostly fills the frame (it doesn't need to fill the entire frame, but it needs to dominate the center.) Then pick "custom white balance" as the white balance setting on the camera. It'll ask you to select a reference photo from the card. Pick the shot of the gray card. Now... everything you shoot in that box using those same light bulbs will get the white balance corrected perfectly.
If you shoot in RAW, just take a photo of the gray card (doesn't even need to be close nor centered). Then shoot your products (don't worry about wonky colors at this point.) When you import the photos into the computer, you'll "white balance" the shot of the gray card. But most decent post processing apps (Photoshop, Lightroom, Aperture, etc.) will let you "copy" the white balance adjustment required for one frame and apply it to any other shots you took. That will result in all those photos having perfect color.
ALSO... be careful about trusting your monitor or printer. Unless you've bought a calibration tool and calibrated your monitor and printer, then the colors you see are probably not accurate. If you adjust things so they "look" normal to you, then everyone else will get wonky colors on their monitors. I color-calibrated my monitors and my printers using an X-Rite ColorMunki.
Brands don't matter so much here (well... actually since a monitor calibration tool includes software, people will declare that they prefer one over another because they like the software and ease-of-use features, but for gray cards... it's just a neutral gray surface and there's normally no software involved.)
