I may be a bit biased - but thats a LOT of micromanagement. You might find yourself overwhelmed - even after a lot of practice. My suggestion is to keep it a bit simpler - perhaps the holy trinity - healer, tank dps dps dps?

Also - get solid hardware - I suggest Vetra's - they are not cheap but they just work. The software may work for you but YMMV. Put thought into what you want to do BEFORE you buy anything - it will save a lot of hassle later on.

Above all else - have fun with it. Just don't expect it to be easy at first. It takes a lot of practice.

Oh, lastly. Put your monitors together. The closer the better.
