I wouldn't worry too much. I've done two types of restores: a full TM restore during a fresh install, and manually copying over files after the install. As someone who does some tweaking of my system (I love UNIX), I prefer a full TM restore to try to get as many settings and such as possible (they don't all always make it...). I've had great success both ways.
In your case, you could always try the full restore from TM, and if it doesn't work, just open up your backup in Finder and copy over all the stuff you want. In fact, as long as you just stick with stuff in your home folder (Documents, Music, Videos, Downloads, etc), you'd probably be leaving your sleeping problem behind. That's what I'll be doing (going from 500GB HDD and 128GB SSD to whatever the new retina 13" base config has - I'll need to pick and choose what to keep - the rest stays on the external drive)
As long as you don't wipe your backup drive, things can't go *too* wrong.
