Your Canon choices are very out of date; the D30 is an old 3MP body that "started it all" for Canon,and the follow-up model was the Canon D60 which could barely focus in many indoor situations and was made for only about six months, and to correct the horrible focusing system, Canon introduced the 10D. Maybe you're on a budget, but I would never willingly select a D30 or a Canon D60 or a Canon 10D in the year 2009--all of those cameras are easily beaten by the newer Nikon's D40-D60-D80-D90.
And a point and shoot digital for SG work? Sorry, but the built in lens issue is one you need to overcome. No offense, but the 'research' you have been doing has been turning up some very poor solutions for both lighting and cameras,and it seems that you're resisting all the actual, good,solid,experienced advice you've been given by avtual,real people who know how to shoot, in favor of some type of on-line research where one easily-added feature (intervalometer) is overriding your choice of a better camera in favor of a point and shoot,and your fear of flash has overriden all the benefits and ease of monolight flash units.
One of the biggest problems beginners have is that they don't "know" what they really need, and they start looking for "features" and start spending hours doing on-line research where criteria are entered,and a computer spits out information, so I'll give you a bit of advice: go to an actual photography store and look at some cameras. Handle them. Snap a few photos. Compare actual, real cameras,and ask the sales person to show you each camera with both the "kit lens" and with the a better-quality lens or two. Right now, your research program is turning up a lot of dead-end choices.
You need some actual experience to make good,solid choices, and when those of us with actual experience try to give you advice on lighting, you disregard that advice and buy a fluorescent shop light...
