If you want to cut some weight there are a few options for you. You need to know whether you are sensitive to stimulants to begin with. If you are, then CLA and L-Carnitine are safe and stimulant free alternatives to thermogenics (fat burners). CLA is a good fat which starts knocking out the bad fats while at the same time maintaining your lean muscle. Carnitine is an amino acid which will naturally help boost metabolism and use fat as an energy source. They are gradual and might take 30 days (varies) to notice some decent results.
If you want the thermogenics for quicker results, there are a lot to choose from and I wouldn't recommend one without first asking you some questions about your goals and sensitivity to caffeine.
If you are in OC, you can PM me and stop by at one of our GNCs and I could go over some good supps for you. Good luck man.
