Welcome aboard. It's been a long time since I lived in the UK but I don't believe there is anything you'll have to change beyond changing the headlamp so it's "left dipping." You have the stock exhaust (muffler that it) so that should be acceptable. When I lived in the UK there was no emissions testing but I can't speak for the present.
I did things a little differently than you in that I bought a motorcycle in the UK and brought it back to the US. I had no problems at all and I don't even recall changing the headlight but that was a long time ago. The US Customs guy at the airport simply wanted to know what was in the crate. I told him it was a motorcycle and he said OK, signed the papers and walked off. I bet that wouldn't happen today!
Good luck with registering it for Her Majesty's roads.
