My new spider (around 2.5 months old) has a slight wobble, which is more noticeable when he's "excited" or nervous... he's a pretty outgoing snake, though, so I notice it mostly when feeding or letting him roam free. It's just a slight shake - no offense intended, but it's kind of like a human with Parkinson's disease. Anyway, since the bee morph is part spider, I'd guess that is what your boy is doing. From what I hear it's not a big deal, as long as they're eating and pooping/peeing normally. As for the shyness, that should get better with time and patience. My babies are still pretty shy, but seem to getting more confident with every handling session. Keep at it!
