1. That will depend on whether an exchange is interested in listing them.
2. You can do everything with pocketsend. Just start a comment with pocketsend:<amount>@<account>, <optional memo>.

So to check @siddartha's balance, I'd write
pocketsend:1@siddartha
and then a bot will give a confirmation of my balance and your balance. This costs a 1-token fee.

If you want to send some to someone, obviously just increase the amount.
