They are all P2Pool, so no account needed (or even possible).
Just use CNC wallet address as username and "x" as password.
Payments start shortly after you start your miner
Is it normal to get whole bunch of Stratum requested work restart?
Yes, it is. And diff for every share is a bit higher than in a pool, so you don't see "accepted" that much.
Doesn't affect payout, you get more for every share, that compensates.
I always have very good payout for P2Pool, never lower than calculated unless internet connection is crap.
