Definitely look into getting a better CPU heatsink. Preferably something with HDT (heatpipe direct touch). Xigmatek and OCZ are the main ones to look at.
You'd probably be fine with DDR2-800 if it's any cheaper. That would give you 1600FSB (double stock) so that should be plenty and most DDR2-800 can get up near 900 (1800FSB).
If you can push your budget, I'd go with a Corsair VX450W PSU instead. If you look on DirectCanada at one of the reviews on the Sparkle:
