As far as controlling the smell... well, the males smell worse than the females. The smell seems worse in warmer weather when they drink and urinate a lot more. There are a few things you can do like change or add bedding material more often or adding a little kitty litter to the bottom of the cage to absorb/neutralize the ammonia smell. Some people have had success adding a little vanilla extract to the drinking water.

I clean all of my rat cages once a week. However, I think it depends on the size of the enclosure and how many rats you keep in each enclosure.

Rats should be at least medium sized before breeding. You don't have to worry so much about the males. Either the females won't allow them to breed if they're too small, or they just won't be "ready". However, females need to be a certain size or else you will risk birthing problems and possibly death. You should only need one male as they can handle a number of females. I pair up my male with seven females rotated weekly. Also, you will need at least two enclosures as you will want to separate the females before they give birth. Rats are able to get pregnant shortly after giving birth which can be very hard on the females body.

Good luck!
All good info! Although I would get a second male as company for the other guy. Just me though..

I am considering mixing in some Pine with the Aspen to see if it smells a little better. I do notice that mid week the Aspen gets a weird smell. Not exactly dirty but not that pleasant. I think it's the brand I have been buying. I am also going to try giving them some newspaper to make nests. Anything to keep them busy and stimulated.
