Hi Shelia -
Congrats & welcome to the forum! I'm with ya -- it is a little overwhelming in the beginning trying to figure out where to start and then you start to think of all of the things you have to do. BUT it's ok. The good thing is that we have this forum to turn to and everyone is so supportive! Just do one thing at a time and you'll see that everything will come together.
Good luck with you planning and don't foget to have fun!
