Buy and read "Farha on Omaha". In his PLO chapter (there are two others: one covering Limit Hi only and another on Limit Omaha 8) he advocates a very aggressive Small-Ball like strategy for PLO cash games. Sammy is one of the top PLO players alive (maybe the best, I don't know). I don't play much PLO myself, but the book and its advice seem strong. He advocates his style but also balances with a more straightforward style so you can see the differences and choose the right style for you. Be warned though, his style is very prone to large swings so you'll need a bigger bankroll.
There was a good article about it in the October 2008 issue of Poker Pro Magazine. I tried pulling it up on their website to link you, but I encountered an error. If you want to dig around for it, here is their homepage: http://www.thepokerpromagazine.com/
