Too Many Questions!!!

Hello
I just purchased an 88' 4 cylinder mustang convertible. I habe always promised myself I wouldn't have anything less than a V8, but I really like the convertible. I think it looks really good. And I like the gase mileage; I have never had this good of gas mileage before. I was just wondering what I could do to give my car some extra power, without costing me an arm and a leg? I also need some insight on how to pull out dents; I really want to this job on my own. Also, the back window is gladd, but the person I bought it from, forgot to unzip the window before putting the top down. It did not break the glass, but the zipper was pulled most of the way off the top. How do I fix this; glue? And , I want to replace the interior, would anyone know how much this would cost, and how would I go about doing so?
Thank you for you r time and effort, to help me solve my little delemmas. I really appreciate the insight.
