MNs are always 10K. Each MN will pay out as shown here: http://178.254.23.111/~pub/DN/DN_masternode_payments_stats.html

Note that there will be a block reduction from 15 to 10 PIVX in the next few days, so the payout will decline by 33%.

Staking rewards are also listed on the same site, but the frequency of receiving a stake depends on how many coins you are staking. With 1000 coins, maybe once a week or so; with 10K, almost once a day. The see-saw mechanism is designed to balance rewards between MNs and staking. Because there are a lot of MNs now (almost 2100), staking is almost as profitable as MNs. If the MN number dropped, staking would be relatively less profitable.
