First, ignore Mike. In fact, ignore all the men in this post, they are idiots.
Second, is there anything she's suggested an interest in lately? Like a movie she mentioned wanting to see or something she wanted to do? That can give you some easy ideas.
Dress nice but casual. Jeans. A good shirt. You're hot, so you won't have too much of a problem there.
Don't come on too strong, especially if it's a first date. Don't do anything physical without making sure she's okay with it. And make sure she knows what you're comfortable with too.
Compliment her.
Flowers are good, if she likes flowers. People in this day and age don't worry too much about flower language, so I don't think you'll offend her if you do get her flowers.
Don't talk about politics, religion or past relationships. Either stick to getting to know her, or if you were friends already, just keep the conversation casual.
For dinner, if you do dinner, pick somewhere reasonably casual but also not too much so. Don't take her to McDonald's.
Going for a walk can be good, but keep in mind the weather. It's starting to get colder. If she seems cold, offer her your jacket. You'll probably be fine without one.
