The first one seems to be an attempt to increase the amount of points scored in a game (as they did several years ago with the hand checking rule). I would think more points and more dunks would appeal to the casual fans a lot more than maybe, players working on their free throws, jump shots or any other of the boring fundamentals.
The timeouts will never happen. The league is at the mercy of the TV networks. Look no further than the playoff scheduling if you don't know what I mean.
I wish they'd get rid of of the charge circle. I get why it's there but I think it forces the refs to call something, no matter how minimal the contact. Let there be a little contact around the rim.
