Flowers are too much for the first date. Wait until the third date for flowers. You don't know if it's even going to work out.
Whatever you do try to get to know her. That's why I like a quiet restaurant or a walk in the park on a date. The date should be about you 2 getting to know each other, not watching a movie. Well, younger people might be different. A movie might be less nerve-wracking, but you have to get to know each other to determine if it's even worth it to continue dating.
Everything else sounds good.
-say goodnight and get a kiss if possible
You don't "get" a kiss, you take it. Kiss her on the lips, lightly, once. It's not time for tongue hockey (yet).
And for pete's sake don't be groping her mommy bags either on the first date. Sit across from her at any restaurant. Not next to her. She doesn't know you and doesn't want to sit next to you, unless she invites you to sit next to her or she sits next to you on her own.
I have a long time interest in psychology, specializing in relationship dynamics for 30 years.
