Yes, the kiss is important, if the pash doesn't feel on, then its not. A kiss to the cheeks or forehead, or even the hand (for some class) are always a nice touch and something that will set you apart from 'other guys'.
Ask questions about her, women are far more comfortable when they talk about themselves, and don't use the stupid things like 'oh your eyes look wonderful', that's as bad as 'your tits are tops', complement her on her dress sense or her smarts, sounds dumb but it works.
Always leave your plans up in the air, never make firm plans, its hard to sometimes, but keep your options open, women love spontaneous things, so plan for movies or something and then say lets just go get some dinner have a nice quiet night out. Never do the movies, they suck, you can't talk to her and get to know her.
And don't expect eveything to happen all at once, if you really like this girl take the time to get to know her, don't keep thinking about 'banging her', and look in her eyes when you talk to her, not her mouth, tits etc.
