From what I can see on product information on the internet you should probably just need to do a weight check and be mindful that you are switching from a jacket to back inflate BCD. Also, just a friendly reminder, if you are using new equipment make sure to change one piece at a time and make your first dive with it a fairly simple one until you get the hang of it. Better yet, test it in a pool or on the shore first (if you can).
Possibly. Scuba Dive Magazine sometimes includes inherent buoyancy ratings when doing BC reviews. Basically it is the tendency of the BC to float. Negative or neutral ratings you would not have to change your rating. If you had a positive rating of say 2 lbs., then you would have to add 2 lbs. to your normal weights just to offset the inherent buoyancy of the BC. Standard weight check with your first dive should be fine.
You can wight check the bcds in a pool. Lt them get good and wet, then weight it each for neutral buoyancy and compare the weight needed. It will only take a couple of minute and tell you the equipment related difference in buoyancy.
