Don't even consider starting without formal training, no one can or should suggest your starting basal rates other than your doctor.
As a first timer it could take from a few weeks to a few months for you to get used to the pump and become stable you need support at this time.
You do not mention where you are from, I'm sure that this pump is not yet approved for use in the UK or Europe, so guessing your from elsewhere.
Edit "Opps forgot to say, welcome to the world of pumping, in around 50 years of IDD it was the best move I ever made"
