Question Regarding Reaper And Vst

A question for someone more experienced that me ........I've just started playing with Reaper and have only experimented with Acid Studio up till now
Say I've got a 16 channel vst plugin .......how do I associated my different midi tracks to an individual track in the vst , without having to load another vst copy each time ........I seem to only be able to get the vst's #1 to sound and none of the other 15 channels ????
One other quick question........Is a Gig of RAM sufficent for running several plugins at once , or would more be preferable
I run ezdrummer and I've read it's very system heavy
Any help or advice is most appreciated
