Congrats Gary! A 10" dob is a great place to start.
Don't forget the red torch or headlamp if using a book or chart at the scope a white torch will make night vision impossible to preserve.
I assume Bintel have done a collimation on the scope, so should still be OK to just use the laser to adjust before observing, at least the first time. A good idea though is to learn the whole procedure of collimation from scratch. Having said that there are lots of ways to successfully collimate a scope. Here is my procedure that I used on my old 12"

Although this guide recommends against lasers, a good laser is still very useful as a final check or tweak at the start of each session.
Cheers
