Superior Spider-Man

So, I have up to issue 3 of Superior Spider-Man, but I had to drop it due to not having enough money. I want to start reading it again, though--since Miguel is going to be in it (well, presumably Miguel, given it's Spider-Man 2099). I was just wondering if someone could tell me which back issues are really necessary to pick-up to be caught up. Thanks in advance!

P.S. Please don't spoil anything!

I plan on picking up the trades to catch up. I bought the first trade and enjoyed it. It should work out cheaper with trades as well maybe.

I kind of like issue 5 of Superior Spiderman is revealed to be Bill Clinton in disguise. than in a later issue they remove the Bill Clinton Mask to reveal he was really Lex Luthor the WHOLE TIME.... ahh good writing.
