setting up my control surface to control vst instruments and efects? please help!

hey all, for though of you who don't know me i'm trey from the uk and i'm totally blind. i'm running 64bit reaper on 64bit windows7. I have a control surface that outputs midi note and midi cc's as standard so far i have managed to set it up to control aspects of the track view such as play/stop and record, how ever i don't know how to set it up to control the settings of vst instruments and efects please could some one explain to me how to set it up to control vst instruments and effects? your help with this question would be most welcome!! kind regards trey.

Also for quicker workflow right click the arm button on any track your using a controller on and choose " Auto arm when track is selected". This is of utmost importance. :)

thanks for the tip about track arming man :) does the option when track is enabled refer to the plug in only being controlled by your control surface when the track that the plug in is on is armed? your help with this question would be most welcome kind regards trey.
