fingering problems! please help!

[falling4ever3]

Recently while in choir we had freetime, me and some of the other students started playing the piano. I played Bettoveen's (sp, sry )5th, and my choir teacher who plays the piano very well asked me if I took lessons, and I said no. She said she could kind of tell because my fingering was bad. How can I learn proper fingering with out a teacher? Is there any good websites? Please help! I'm still a beginner (the most complicated piece I know is Menuet by Boccherini) but I'm afraid that my poor fingering might result in problems and bad habits later. I would appreaciated any advice you have on this subject, thanks

Also, I have been playing the piano for about 6 months, and the most complicated piece I know is Menuett by Boccerini, is that fair progress? Should I be playing better by now? Thanks again,
