Multitabling, what software reqd?

I'm presently playing 2 tables on Party poker. With the blinds often playing "for free" i find myself too busy to do more than 2 tables. Yet, i read of others playing 8, yes 8 tables . How do they do that. What software manages all the details with the blinds you don't really want to play but get in to the hand for nothing with.
I know of Poker Tracker. Does it run and give you stats while you are at the table, so you can see the stats on your opponents AS YOU PLAY!! what an edge that would be. Am i light years behind the times.??
