Yes, our HQ is close to the OP and I do hope they consider us as one of their options. It really is hard to beat what we offer for a regulator package when you factor in all the benefits and improvements, like the free first service including labor and parts. That alone saves most divers $150-200 at the first service interval. However I am sure whatever the OP picks they will be happy.
For some non-specific general advice, there are several specialty options out there for mouthpieces that will work with any second stage. SeaCure custom mouthpieces get great reviews, and you can find other options from Innovative Scuba, Titan, etc. Each includes various sizes if you need something a little bit smaller/larger. You just have to try a few options to find what you like best, as they are a very personal item and opinions vary.
As always, for a BCD option I recommend a BP/W. That is what I teach in, and what I find to be the best option for almost anyone. You get maximum adjustability, ease of fit customization, improved stability with the tank, and your trim will be better with an air cell behind you instead of wrapped around you. They also tend to pack up smaller for travel, and some versions can be very light weight. You do need someone to properly adjust it and show you a few things though, so consider that as well.
I am sure you will have lots of shops tell you it is only for technical divers, Jacket BCDs are better, etc. I have come to the conclusion that shops like to sell jacket style BCDs because their margin is higher, they have no experience with BP/Ws, and it takes no effort to size and fit a BCD for someone. They make more money with a faster solution that requires less work on their part, even if it isn't the optimal solution. So of course they recommend it more.
Overall, look around, see what you like, and then go with what you will feel most comfortable with. There are many great options out there to choose from that are safe and reliable. At the end of the day this a hobby for most people, and what is most important is that you enjoy yourself.
All the best,
