Welcome to PT! I have two babies Jack & Sunny who were from a Cat's Protection shelter here in South Wales. You can check out their website here if you haven't heard of them, they're THE cat charity in the United Kingdom
www.cats.org.uk

You can see a picture of Jack (naughty mummy's boy!) and Sunny (naughty daddy's girl!) below

Mowgli is beautiful and very handsome, I'm sure you'll have a lot of fun with him growing up!
Socialising wise I think it's best to introduce him to one new person at a time, so he can get used to smells and different situations. Bengals are supposed to be Extremely sociable animals so he will probably be a doll in the future! Let him do things at his own pace, as of course you can't force a cat to do anything it doesn't want. (and tha'ts why we all love them!)
Just take it slowly but surely and I'm sure he'll grow up very confident.
Interaction with him yourself with playing etc is paramount for his development I think.
