WELCOME, gerbils!
(btw, I had 8 (successively) gerbils growing up... I was a terrible, terrible gerbil owner! )
My siblings and I were raised Catholic, and only one of my sisters waited for being baptised. Interestingly, she is the only one who is still Catholic (she did get baptized many years later). And she is one of the best examples of a Christian you could find. (The rest of us went protestant, but we all get along extremely well!) So, I say, it should be a general principle that our convictions should bring us to a point of such a deep commitment. And even so, you may find that there are reasons that you discover, as time goes by, for redefining your commitment.
I think you would like to peruse this site before you get baptised. It is ONLY quotations from the Watchtower, no commentary, on a variety of subjects. It is quite interesting; food for thought.

Edited to add: for some reason that link sometimes has horrible formatting when I click on it. I hope it works for you. If not, I hope this one works: http://quotes.watchtower.ca/admin-site-map.htm. Or type in Watchtower quotes into Google, and select the second entry. Hope it works!
