Some links I like on Judaism are aish.com and
www.jewfaq.org. I think these are both Orthodox though, but still a good source of knowledge. It is good that you have done some research on Judaism. The first thing you will need to do is contact a Rabbi. You said you wanted to be Conservative, so go here and locate a Shul in your area
http://www.uscj.org (go to locate a Synagogue)
After that, e-mail or call the Rabbi- it is tradition for a Rabbi to turn a possible convert away three times, but I don't think a Conservative Shul would do this, but if they do don't get discouraged just keep coming back until you get a Yes. ~smiles~
Most Synagogues aka Shuls have conversion classes, so you can learn more about Judaism. After a year of conversion classes, you have to decide if you would like to convert or not.
If you haven't been to Shul try a few out to get a feel for the service or what kind of Jew you may want to be. Another thought, being Jewish is about community, so try to get involved with things like JCC, so you can meet friends and such.
Good Luck with your studies. I wish you the best.
