Nice to see you're exploring new things. Only thing I would suggest is try experimenting with making one of your own songs as well, it doesn't have to be perfect and if you don't want to submit it that is fine. I'm just saying don't limit yourself to remixes.
More or less I just play around with notes until I find a melody I can work with.
I have always used FL Studio, I'd totally recommend it.

Music editing, huh?
I trust that you'll be fighting against the Knights of Dubious Dynamic Range in the Loudness Wars, right?

But of course! I cant let those fiends win, after all!
