How can I get long legs?? And this other stuff :)?

I want long legs that are firm and fit :) I'm 5'2 I also have this stubborn lower abdominal problem I seem to do alot of crunches and believe me when I say I do them properly but yeah 'the pooch' won't go away! And the love handles! I hate how most of my friends are fit..Almost there but that's the only problem.
