I currently have a Canon T1i, 430 ex ii, and recently made myself a backdrop stand and bought a black felt material (which works great, at least for my purposes). Anyhow, I find myself wanting to get more material for backdrops and have concerns with lighting. At the moment I'm just using the 430 on camera pointed at the ceiling or a wall (if it looks good).
What should be my next step? Photos of my daughter lost in space (black) have already gotten boring for me. I am on a (VERY) limited budget, but could possibly talk my wife into some kind of smaller purchase, or i'll save, whatever...I just would like to know the next logical step for me.
Some specific questions:
Are flashes absolutely necessary? What would just having extra lights (like shop-type lights) do for my photos if anything?
Is there any way to get the seamless white look without having to purchase more flashes? (specifically, i was wanting photos of my daughter eating cake for her 1 year pictures on a total white background)
Will any type of fabric background work (in terms of shadows, etc.) if I continue with only the one flash on camera?

Thanks for any insight you can provide! I'm lost in this new world of photography!
