I'm here at the global game jam, trying to see if I can get .NET 4, C#, and XNA 4 installed before the jam starts. =D
Sprites that are a power of 2 are great. If I recall correctly, modern graphics cards can use non-power-of-two textures, but back in the day they might not work on some cards.
HOWEVER, I would expect Game Maker to draw sprites out of a sprite sheet, and you could presumably make the sprites inside the sprite sheet whatever size you wanted. I don't know for sure though. I still need to run through the Gradius tutorials before the jam starts to refresh my memory.
Doing the XNA thing, eh? I always hated just how convoluted the install process was for it. At one point their docs were a complete mess that lacked any semblance of checklist with links. So bad! Haha.
This year we're doing Flash for the first time. We did XNA for the first two years. Here were the projects from the last two years:

Excited for this year again! Picked up a load of vegetables, fruits, and nuts for supplies.
