Welcome to the boards and very exciting about you guys having your first trip!!! :sohappy:
First off- don't stop trying to get CRT. Things open up all the time...and while it's not always easy and may take weeks or months to find a spot... persistence pays off. It sounds a bit obsessive, but I have been known to check the Disney dining website 100+ times per day if it's an ADR I really want...especially if it's for my girls.

If possible, try and be flexible with the time/meal as that will afford you a much better chance of getting an opening. In the meantime, I'd suggest booking Akershus or dinner at 1900 PF if nothing at CRT is open right now and there are slots open at those other locations. We timed BBB w/CRT on our first trip, but I also have friends who did BBB and then hopped over to Akershus for dinner. All in all - it's one of the really sweet experiences a little girl can have at WDW. Assuming nothing falls through for our Nov trip- I think both of my girls wil do it this time (my younger one was too young on her first trip).
Secondly, have you considered getting a bday cake? If you can get into CRT, they even have a special pkg that comes with a princess topper on the cake... otherwise you can come up with a custom cake idea. The cake in my avatar was made by the Contemporary bakery and delivered to Chef Mickey's on my DD5's fifth birthday. Feel free to PM me if you need more info on ordering custom cakes.
I also agree with getting out and about on that first day. On our girls' first trip, we arrived at our resort around 1pm and we were on the first boat over to MK as soon as we were done getting into our room.
While we've only done MVMCP, MNSSHP is on my list of things I want to do with my kids...and it sounds like a BLAST...so I'd probably do it if I were there. It will probably be a sell out for at least some of your trip dates, so you'll probably want to decide early and figure out which of your dates would present the lowest crowds (once the dates for the party are released).
Most of all- don't stress too much...the planning is part of the fun!
