Poker Calculator from Carbon

I have been using the poker calculator from carbon but not sure what columns I should be focusing on. Does anyone have any suggestions on what I should be looking for? I have been mainly looking at AF aggressive factor and at VPIP which is voluntarily puts money into pot.

How is the traffic on Carbon? What is the easiest way of deposit on Carbon?

It is not bad about 6K people all day what I like is the range of tournies they offer. As far as deposits I am not sure what the best way is, I have deposited using visa but I heard it is not available anymore. I have got my roll through grinding freerolls and funsteps. I think WU is the best from what I have heard but the min deposit is 100 bucks.
