Flstudio live performance questions

Ok I am getting close to wanting to play out live. But I have some questions.

I am currently laying out my songs wav's in the playlist of my project . In between each song I have a pad, a kick and a tempo change. I was planning on making my set just one long wav file and then use my FLstudio laptop , and having a keyboard to play a few pads and leads along with the songs.

Does this sound like a logical way to go about playing live?

Basically I want to be almost like a dj but maybe play a lil bit along with the songs

I just watched a guy whose music is similar to mine do a live performance last night and all he had was a laptop , mic and a projector. I was thinking of having a keyboard up there just to be a lil more interesting even though I am a crappy keyboardist. Any ideas and thoughts would be appreciated.
