The thing is though is that I am not really training for anything in particular (eg a comp), just want to have bouldering as an ongoing hobby and hopefully improve over time. You seem to be saying that I still should break it down into meso cycles etc?
If you are going to pursue a physical pursuit with a significant degree of intensity then yes, periodise. With many young people the problem seems to be to get people to pull back, rather than getting them to train hard - and this goes for resting between sets as well as resting between training days, or resting over a training cycle.
As for tendonitis, yes there are rehab exercises (exercises that should also be done as prehab), to resolve the condition including internal and external shoulder rotatations using therabands and wrist work (wrist push ups, rotations and reverse wrist curls), to resolve imbalance in the forearms.
