How to get the 80's sound

Drums:
You can use the Pop Rock kit from EZ Drummer (or the DFH for more toms, but more EQing needed) with a high reverb on the snare, and some EQuing so that it sounds like a "blast". Good reverb on the whole kit, high hat bit higher than usual and overheads bit lower.
Phat, borderline electronic bass drum with a short reverb.

Piano: old "Steinway-like" should do the trick.

Synths: Put SAW on everything

General effects: Chorus, (vocals, solo guitar). High reverb on guitars with a rather clean sound (the heavier the sound the harder it is to add reverb). 2 overdubbed guitars with little distortion is better than 1 heavy guitars (80's style...)
