The Micro if you look doesn't have any inputs. Its simply an output sound card (a pro tools requires Digi Hardware at all time).
Pro tools is, IMHO, the king for major audio editing and mixing, but for what you are doing maybe something like this would be better suited:

Comes with cubase LE.
BTW, pro tools LE is the same whether you get the micro or their higher end 003 so the software isn't any more slimmed.
