Any of you guys know if those two listed bikes are decent?
Main problem with both of those bikes is the fork. The XCT fork isn't a good one: http://www.bikeradar.com/gear/category/bikes/mountain/product/review-giant-revel-0-11-42756, and the XCM on the Norco is even worse. That said, the XCT reviewed there is the 26er model. Whilst the 29er version still wont be a particularly high end fork, it might be better than the old version.
If I had to pick I'd probably go with the Giant as the brakes and the gearing are noticeable better than that of the Norco. At the end of the day if you enjoyed the test ride and didn't notice the limitations of the fork then you should be perfectly happy (and if you want you can always upgrade the fork in a year when your skill level exceeds its capabilities).
how do i clean this rust
also, my bike is making constant sqeeking sounds when i ride it, i have no clue what's making it
You wont get the rust off now. In future, make sure you wash your drivetrain thoroughly and rinse it properly whenever you've ridden on the road (especially in winter). If you get salt on your drivetrain and it stays there... that's what happens.
Like ch0mp says, clean it with degreaser, lube it up (just your chain, not the cassette, if you do your cassette it'll just attract dirt) and then wipe off any excess.
