Having not actually watched you paint, I can only guess, but it sounds like you put the initial coat on too thick, and any coats you put on top will do nothing to knock down the original ridges. As others have already said, you're going to have to sand out the ridges and repaint.
Don't skimp on the roller covers - yeah, you might not get more than a few uses out of one before it starts to shed fibers, but it's still worth the peace of mind and lack of frustration to shell out a few extra dollars and maybe if you take care of them (and don't use tomato- soup red or tuscan orange - trust me) they'll last you for a while.
And don't buy that line o' crap on those roller covers treated with Teflon. They don't clean any easier than "regular" rollers and they do seem to shed fibers faster. Don't just randomly choose a package at the Big Box Store, but go to a genuine paint store and ask what they'd recommend as far as quality, lasting rollers.
One thing no one has mentioned yet, but I've found helpful, is not to roll in one direction, but change it up - up and down, left and right, at a 36.2 degree angle. My experience has shown I'm less likely to leave marks or miss a spot if I do that.
The gauge of not rolling to large an area (and getting the paint thin) or too small an area and making it too thick...well, that only comes with lots and lots of practice, and me? I'm still an apprentice...
