Reading through this thread, it seems like you're pretty much set.
The only bits I have to add are:
1) Get one or two nice terry towels for your bar. I like to lay one down over the top of my bar so that when I spill while mixing, I don't make a mess. I have a couple of branded rectangular pub/bar towels (from John Bull Bitter and Newcastle) that work great for my more casual bar setup.
2) Remember that not everything in your bar lasts forever. Vermouth goes bad (like an open bottle of wine). Sodas go flat if opened. I steer clear of economy size mixers in general - - you "save" money up front, but they tend to go bad if not used and, frankly, I think that large plastic bottles and tubs are an eyesore for a thoughtfully composed bar. Small glass bottles of tonic water, ginger ale, and club soda are best in my opinion.
3) I can't remember if I spotted one in this thread or not, but do you have a muddler? Muy importante for mojitos and many other mixed drinks.
Hospitality is one of the greatest gifts we humans give each other. Separates us from the other apes.
