I have to add that it's really, really
worthwhile to take part in any open rituals or pagan events you can get to. Reading about different paths and practices is one thing, but you'll learn much more if you experience them. These days there are Pagan Pride Days, pagan festivals, pub moots, open rituals, etc. all over the place if you look for them. This is where the Internet really comes into its own, and there are usually regional Wiccan or Pagan newsletters that list events. Most are free or by donation, and most are quite kid-friendly as we are all about fertility. (Our local Pagan festivals are always running wild with kids!) It's pretty intimidating to show up at an event where you don't know anyone and don't know what's going on, but I've always found people to be friendly and pretty welcoming.
I've recently discovered pagan podcasts, and I think I've learned more in a couple of weeks than in 25 years of reading! My current favourites are Druidcast
and A Pagan Heart in Maine
. Lots more are listed at the Pagan Podcast Index
And finally, don't worry about whether you should have Celtic gods, or Greek or whatever. You can choose one pantheon if you like, or move across them according to need or occasion, or worship the God and Goddess without being specific. The Goddess On Duty will hear you even if you don't know what name to call her!
And as for paths... isn't this
