What should have high priority though is certainly:
Laboratory of course, that's always #1, no brainer :)
Build the new buildings
Upgrade Mortars and Wiz Towers (Splash defenses are really important, no matter what TH level)
Army camps and Air defense. (Air defense has the same priority as Mortars and WTs for me)
Then the rest, as you like and as you have your resources available. Don't forget to drop your extra gold into walls, they DO matter, and they're not hard to get to Level 6, don't give up, it's a pain in the ***, but Level 6 and 7 walls are really not that "hard" to farm.
