First I have a razr naga epic that I use and have it set to numpad keys so those are my right quick-slot bar with all my heals being on that bar
For my top center bar I have 1-6 alt-shift[1-6]
[1-6 with main attacks alt shifts with cc and a few random abilities that I used when I was on beta that I can't even recall right now]
bottom center bar i have shift 1-6 and alt 1-6
[shift 1-6 for overload stun dots and alts for consumption med packs etc]
On the left I put my aoe attack pvp items such as stims/med packs throw huttball buff and seethe and I use shift plus the keys on the side of my mouse so w/e the numpad keys are
I'll post a ss when I can get back into game but it worked for me all throughout closed beta relatively well
