You're going to get too strong too fast, so unless your training partners are superman and the hulk, nobody will want to train with you. We have equipment that allows for very easy training partner assisted negatives of any exercise, but we're the only ones in the state of texas and, as far as I know, there are only 5 states that have such equipment.
That said, isolation movements plus no-dips/chins are prime candidates for this sort of work.

Yah weighted dips and pull ups seems like an excellent start. For dumbbell negatives, for chest you could do really heavy pull overs starting from the chest and moving back then dropping it. For shoulders I'd probably say that the safest method would be the smith machine but that doesn't say much for the stabilizers. Negative Squats would be great as well.
