So I am trying to convert my bike to 9 sp. Is a 8sp LX derailler reuseable for a 9 sp or will i need a 9sp derailler?

why are you changing it? 8 speed stuff required less adjustment then 9 speed
shifter yes, dérailleur no.
8 and 9 speed dérailleurs operate within the same range; that is, the cassettes are the same width (note: gear spacing is not the same). the shifter needs to be replaced for 9 speed because they are indexed for a specific number of gears
This. Your derailleur is fine. You'll need a shifter, a cassette, and a chain. Job done.
yup. Remember when 9 speed first rolled around and hubs were advertised as 8/9speed compatible? its because both cassettes fit.
I thought the chainwheels were narrower to accommodate the narrower 9 speed chain? IE 9 speed is backwards compatible, but 8 speed is not. It's probably splitting hairs anyways, but am I wrong?
regardless hold onto your old stuff...there are people out there with a preference for 8!

chainwheels? wtf?
you mean dérailleur pulleys? i ran an amalgamation of 9 speed chains on pre-9speed dérailleurs with no issue for years.
IIRC 8 speed chainrings (or chainwheels) had the exact same tooth size but were a tiny bit closer together and the pins and ramps were different too. 8 and 9 speed cogs were also the same dimensions but were spaced closer together for 9 speed. The inner dimensions of the chains are the same but the outer dimension of 9 speed was narrower. 9 speed derailleurs had slightly narrower jockey wheels and cages.
