I've been collecting comics for about half a year now, and I've sort of settled on the characters I like. One them is Deadpool, which will probably annoy a number of you, but what trades should I get? I've currently got Deadpool & Cable Ultimate Collection 2, Dark Reign and #23 to this month's. I'm going to get Secret Invasion, but then what? Recommend me some, pals.

I always recommend this story, this is for anyone looking to get into Deadpool comics. 
 
For trades, I suggest getting all of the Cable and Deadpool Ultimate Trades, and Deadpool Classic Volumes 1,2,3,and the upcoming 4.

"Deadpool Classic Volumes 1,2,3,and the upcoming 4."

I enjoyed the Wade Wilson's War mini-series, but that was an alternate universe.

I don't think anyone can truly call themselves a Deadpool fan without at least reading some stuff from theJoe Kelly era. That's Deadpool at his peak, that's what every Deadpool writer should look at when looking for inspiration on how to write that character. 
 
I can safely say that Joe Kelly's Deadpool was thebest Deadpool ever written. "

Merc With a Mouth
his self-titled 4-part mini that came out in 1993.
 
why don't you stretch out and grab the Flash ongoing series, or Amazing Spiderman....

I'd start with his earlier stuff, like Sins of the Past, Circle Chase, and anything from Joe Kelly.
