Yup, disable posts on flop/turn. (option 37 or 38 on the features menu?) I keep mine on factory medium settings, with a fixed EB at 25M. I too think the game looks much better with incandescents for the inserts--really nice attract mode lights. Black rubbers are fine. There aren't many at all, apart from the few on the mini-pf. White ones there will make it very bouncy.
2 alternative play modes for WPT that I think are fun: Set main mode to Extra-Easy with unlimited EBs, 5-ball. You will have marathon stacked-multiball sessions! The game gets crazy busy on EE.
Also, you can play JUST drop target poker with a friend. Winner is the person who finishes the most drop target hands in a game--nothing else counts. Pretty cool game-within-a-game.
