Lots of great advice on here so far and here's a couple of links to help as well.

https://www.youtube.com/watch?v=idVWobNeGtU Lots of great mixing tutorial videos from Recording Revolution on youtube or go to http://www.recordingrevolution.com You can see and hear what he's doing as he explains how to do it. Then try it in whatever DAW and effects you are using.

Also Coursera has a FREE music production course from Berklee which covers all the basics.

Hope that helps
