Yeah, it's 1 XP for each 6-, plus the end-of-session XP for bonds, alignment fulfillments, and session accomplishments as outlined on page 78. It's 8 XP for the first level-up.
There's a monster treasure table on page 228 that might give you some sort of guideline; according to that table, little monsters might have 10s of coin worth of treasure, moderately large ones 100s of coin. Take a look at the equipment lists starting on page 326 and think about how soon you want the players to be able to afford mansions or castles.
Keep in mind that it's always better to start the campaign giving out too little gold than too much; you can always turn up the drop rates later, but it's hard to go back. ;)
