I think you should go through the Bible and read a little. If you see a particular verse that really touches you, then I would try to get that one.
If you get them, the best places to hide them are your hip (probably best for your astrological sign/birthdate). As for your barcode, maybe on the back of your neck? Your hair can hide it when you wear it down. Just be careful who you might be around when you have your hair up. If you don't want to get it on your neck, I would get it on your other side of your hip.
As for the Bible verse, you can get it on your back or one of your shoulders.
I honestly think you should wait a while before you get anything though because you sound extremely unsure of this and tattoos are not a spur of the moment thing. If you get them when you're unsure of them, you will surely regret it. Wait a little while (maybe a year or two) and see if you still want it then.

With the Biblical thing, I would choose a phrase that you like, and either put it in a different language, or get a tattoo of the book its in, because the phrase is smaller and easier to hide. [ orphans's advice column | Ask orphans A Question ]
