leveling weapons vs questing dilemma

[Snorri]

I've been mostly focusing on my weapons and I havn't done many quests yet.

I'm level 23 now and most my weapon skills are at 14, with grenades at 16. Except pistol is low at 10.

I am getting a bit worried that if I keep up with my weapons training then I will hit 30 and start needing to train staff, then by the time I train staff I will have little time left to do the quests for Rep. Is there any schedual I should be following or a point to which Ishould start doing the quests? Or does leveling get so slow in the 30s I shouldn't worry about being able to fit both in?
