I wasn't saying you were wrong that the controls are a bit annoying when shooting, I was just saying its much improved over the previous versions of GTA. Also, your preaching to the choir about the wiimote, I wouldn't of gotten very far if it wasn't for the autolock-on. When shooting from the car, I generally wait for a straightaway before trying to shoot, otherwise I don't have a chance of hitting them.
And I've also only had to redo a few missions, but the dialog was different the second time through on each one.

To be honest I haven't spent much time in the strip club, I've only gone when required and then I skip through the lapdance so I don't have too stay long. The graphics are pretty far from realistic, so I find it just boring to watch it. I'm not too surprised they only have one or two routines though.
I'm not sure what you mean by running into cars around the corner, do you mean on foot or in the car? If it's while driving, then I've found that I have to constantly adjust the camera to get the best view, which was the most annoying thing for me in the game, but I've gotten pretty good at it so it now doesn't bother me much anymore.
