You'll need to present the old passport at BKK airport when you arrive so that the IO sees the Extension stamp and Re-entry permit. He will then refer to this when he stamps your new passport. Take both passports when you go to your Immigration Office to get the Extension transferred. I've done it before, and it was straightforward. They don't transfer the Re-entry permit; you have to do this at a different desk (free).

Actually the letter is only required if you get a new passport in Thailand. If you get a new passport in the UK it will be stamped when you arrive in Thailand, so won't be blank when you take it to Immigration to get your Extension transferred.

An IDP is only valid if it is held with a valid national licence.

If the baby or child doesn't have a visa, they will be stamped in visa exempt when they arrive at BKK. If they then overstay there is no fine or ban, but when they leave Thailand their passport will be stamped 'overstay'. This shouldn't be an issue, but if the parents plan to live in Thailand and if the child may eventually go to school in Thailand, I would get them an O visa as your dependent and then they can be added to your Extension of Stay.

I doubt the kids can speak Thai

I always report by mail. Currently it's taking the longest time ever - I'd allow 8 weeks!

Not completely closed, but very restricted opening hours.

Is there family/friends who can renew it in the UK for him? I believe it can be done online. Otherwise you might need to get proper advice from one of the specialist agents here.

Presumably your son is using a different passport to stay in Thailand? I don't think a UK passport can be renewed in Thailand without the expired passport. Your son can renew it in the UK when he goes back there.

Currently there are no restrictions between Bangkok and Pattaya. It's a popular weekend getaway for Bangkokians, as at least restaurants are open in Pattaya.
