I am having issues covering cakes in fondant. Is there a trick or hints to not having the creases and having to cut the fondant to eliminate the crease? Can a cake be completely covered without having to "fix" creases? Does someone have a tutorial?

I elevate my cakes, than carefully work my way down the sides about 1" at a time. Once I've reached the bottom, I trim off my excess, than place the cake on my mat and finish smoothing.

there are tons of free tutorials on youtube, along with an infinite amount of tutorials for anything you could want to know/learn about cake decorating.
If you have a little money that you can 'invest', I bought a DVD by Jennifer Dontz that I think is the BEST thing I've ever done for myself to improve my skills.

Before I bought the DVD, I would panic at the thought of covering a cake in fondant because I couldn't figure out how to keep the fondant at very bottom of the cake from puckering and pleating and looking awful!
My first attempt to cover a cake after I bought the DVD was 100% better, and now, I can cover a cake without any worries, or lost sleep!!
