If you want to do those exercised, do them on the lifting days, not the rest days. It's going to kill your progress if you are doing this stuff on rest days.
Also, make sure you are doing weighted chins and dips. High reps are nice, but the weighted ones are much better.
Depends on form. A lot of people strap weight on and form goes right out the window. I still don't do weighted dips or pullups/chins.
Also, you can work on rest days, the key is to not over do it. Rest days don't have to mean do jack shit. You can still do conditioning/muscle stimulation. The idea is to keep it from being on par with a work day.
Something people seem to forget here, that nothing is 100% right for everyone. Some people can get away with doing more, some can't. It's up to the individual to experiment and find their own limitation.
