Hi Chris, and Welcome to the AMD Forum!
Your 2200+, whether it's a T-bred 'A' or T-bred 'B', is designed to run at 13.5x 133MHz = 1800MHz
So you would initially set your FSB for the CPU at 133MHz = 266DDR
You may be able to overclock it higher than that, (and probably will be able to), but that's the setting that you start out with.
On the memory, you can run it at a different speed than the CPU with your mobo, so yes, you can buy 333DDR or 400DDR memory, and set it to run faster than the CPU.
Since all memory is 'backwards compatible' I would suggest that you spend a few extra $ now and buy the faster PC3200 ( which can run at 100 MHz, 133 MHz, 166 MHz, or it's rated 200 MHz = 400 DDR), knowing that it will be 'good-to-go' on your next mobo upgrade.
Or, even better, would be PC3500, (433DDR)... and it's not that much more expensive.
You will also realize an immediate benefit with the faster memory now, because you will be able to run it in your current system with very 'aggressive' memory timings.
