First of all, congrats on your new baby and welcome to the forum, you are going to meet alot of wonderful, helpful peeps here!
This is a chart for the vitamins/cal. ratio :
http://www.beautifuldragons.503xtreme.com/Nutrition.htmlNever heard of the spray I have always used powder, one of the more exp. beardie parents on here may have to help you with which is better for your baby the powder or spray.
As for the pellets, nope, it doesnt need them, as long as your feeding a healthy salad (ex. collards, mustard, turnip greens,ext... the food chart is also in the link I sent you just scroll down the page) and your feeder insects. The food chart will also tell you the best insects to feed.
As for feeding the cricks, give him/her as many as he/she will eat in about 15 - 20mins 2 - 3 times a day. I dont feed after 7pm(Morganas lights go out at 9pm) because I worry about the feeder bugs sitting in her belly all night.
Dont leave any critters running around your babys cage at night, the will munch on him/her while sleeping.
I would also love to know about your habitat setup and if you have pics of your baby

there is a photo section for the proud parents to show off thier beauties!
I hope this helps good luck and enjoy your new sweety!
