Limit Omaha High Question: Betting Structure

[Fairless]

Local casino spreads a 10-20-30 Omaha High game. Generally a very good loose game. The structure is a $5 small blind and a $10 big blind. The first raise can either be to $20 or $30 with all other raises after that being in $20 increments. Example: Open raise to $30 a reraise takes it to $50 total. Bets on the flop and the turn are in increments of $20 and the river bet is a $30 bet.

My question is how should this structure alter your starting requirements? And how should it alter your play on later streets?
