As long as you don't increase the size of your chainrings or your cassette ratios you should use the same length.

so even though my 9speed cassette will be 11-32 and my cranks are 44/32/22 (just like now) the chain will have enough links to get around on the cassette?

hmm funny how that works. thanks

Ummm, yeah, the only difference between an 8 speed and 9 speed is the width of the chain.

It should still work, the derailleur will just move forward farther in the 9th gear

Let me clarify. If your eight speed cassette is an 11-32, meaning 32 is your largest cog, and your nine speed is also an 11-32, with just one more cog in between, this will NOT affect your chain length, because your two critical lengths. (longest and shortest) are not affected.
