There's loads of stuff on both here and Pattaya Addicts about general stuff. I'd suggest going through this Asia section first and reading everything. PA is great, but there is so much info it can be a bit overwhelming. I wouldn't worry that much about travel. You may be fine with walking to your hotel, but I know about 5000 ladies who won't be. So bus/scooter it is. Scooter you make sure to arrange price before you get on. Handy to carry a hotel card around so you can just show it to them. Bus is easy enough. Stick hand out, wait for bus to pull over, get on the back. Mind your head. Press bell/button when near where you want to go, get off, give driver (I think it was) 10 bhat. Don't expect change.
Hotels depend on what you intend doing. Around LK Metro is a good base, and also about halfway between Walking Street and Soi 6. You have some of the massage parlours, a soapy and Metro itself all within pissing distance. WS to Soi 6 is a decent walk but doable, I'd just get the bus mind. I'm not sure how Soi 6 is at the moment. The main selling point was open in the afternoon, chat to girl, take her upstairs, go back down for more beers. At the moment I think they are enforcing 6pm for beer and I don't know if you can just take them upstairs anymore. When I was there it was in middle of a major crackdown so no rooms at all in the bars (ST hotels still good). With it being Thailand that might change on a day to day basis. You'll just have to force yourself to walk down and oogle the females, see what's up.
