I wouldn't recommend the current Guardians. The writer, Brian Michael Bendis, is completely phoning it in on all of his Marvel work. The team has some similarities in membership but there's several members who aren't in the movie and never will be due to movie rights. I'd also say the Chris Patt version of Quill and most comic versions are quite a bit different.
My understanding is that the team most like in the movies is from the 2008 Guardians series, which is part of a multi year galactic Marvel event called Annihlation:

But if you just want some flat out fun comics to read, that aren't reliant on heavy continuity, there's several being published by Marvel. The current Ms. Marvel series is only 6 or so issues in and is absolutely awesome, featuring a young (I think she's 15) Muslim-American woman who finds herself empowered with strange, shape shifting powers. When she first gets powers, she sees Carol Danvers, the current Captain Marvel, and her powers kind of design her costume to look like her.
The current Nova series, which is only 20 or so issues in, is about a 10 year old boy named Sam who lost his father under mysterious circumstances and finds himself empowered by the Nova force. Several of the themes of Quill in GOTG are hit upon in the current Nova series. It has changed writers a few times but they're all really good, at least in this book. It is the best galactic/space book Marvel is publishing.
Hawkeye, by Matt Fraction and David Aaja, is just fun. It is a good read. Go buy it.
