Strauss said he spent 3 months trying to learn how to kiss a girl. It's one of the harder parts of game, but there is a lot of good ideas out there now. You just need to study it. There's lots of good video's on youtube that cover this subject, including Strauss on one of the Annihilation method videos.
There's things you can say, but a lot more of it is learning how to escalate kino and look at her properly, like looking back and forth at her eyes and lips or sniffing her hair, brushing her hair aside, kissing on the cheek, etc.
I just saw this video and think it's great.

As far as date ideas, I don't have good ideas either, but the last girl I took to dinner, asked her deep questions, started rubbing her hand, paid the bill, drove her home, and got invited up to her apartment for a lot of fun.
