Need help looking for some decent golf clubs.?

I am sixteen and just began golfing a fairly decent amont and absolutely love it. My clubs are not as nice as I would like. I recently bought a Cleveland Launcher 460 (2006) for $70 (good deal?) and that is the ONLY club I am interested in keeping. I have no hybrids. My putter looks like it is from the local putt-putt. Should I stick to irons or get hybrids? Are there "good" putters or do they have no effect other than psychological? I do not have a huge budget so I am not looking for top of the line clubs, just effective ones. Just last year my driver was wooden! lol and i had "wooden" woods. Thanks for the help!
