I've had this conversation with several developers and the answer is always the same.
"Pick a target spec and write the best game you can targeted to that spec."
At some point you just have to write the game and go with it. ;)
re: scrolling
Just use 512x512 or 1kx1k and draw each section side by side to scroll the entire bit map world. But you should also keep in mind video ram. 32-64mb should be a target for typical lower end systems.
And also, lower the res of your game and you can create a larger scrolling world with lower res textures. ;)
