I kinda feel like your game will evolve as you go. As a new guy in the beginning you're going to get caught a million times and will probably be on bottom/defense most of the time anyway, either bottom side, half guard, or mounted. So your defense/recovery stuff will come in time. You'll find out what works for you, where your weaknesses are and naturally will want to improve on them. Also you won't always get to play the game you want either (closed guard, rubber guard, mount, etc) because your opponents will keep you from getting to those positions, this will force you to work on other aspects of your jujitsu.
So I feel like work on what you want (as you won't always get to anyway), but at the same time consciously branch out and experiment/work on passing, sweeping, etc. (other positions) -So do both.
If you get to kung fu move again and cant get it under the chin for the gogo, try switching to the hazelette by using the crow bar (kung fu crowbar combo)The crowbar is page 175 of mastering the rubber guard. So far this has been pretty high percentage for me in the gi (blue belt).
Also heres a vid of Eddie using the crowbar at 2:27-2:31 ish
