In terms of calling the show, if you feel more comfortable in the booth and have a good view of the stage, that's what you should go for in my opinion. It should be whatever works best for you and is the most practical.
For the cast, something I find that shows an equal balance of authority and friendliness is to organize some sort of snack shedual for those involved with the rehersal process. Depending on how many people/rehersal days you have, try arranging it so everyone brings in a snack one or two times. I find it not only shows them you're organised, but it's also lots of fun for them to get food.
