As Kaz stated above, don't worry about +hit. +hit is great, but you can roll with 0 and be successful. Focus on survivability first and foremost. When you meet survivability minimums, then you can start looking at boosting +hit.
At this point, your gear upgrades by and large are going to be coming from Kara and the badge vendor, aside from select heroic drops. Keep working through Kara and running those heroics.
From the sound of it your guild is small enough that you have to PuG heroics, which is a crummy place to be. However, the more people you group with, the more competent players you can add to your friends list. When you can put groups together with players that you know don't suck it gets much better.
