I've had a quick look at the save. Another toughish start as although you have a couple of cows, you have no fresh water and the only land expansion through jungle and desert. You are in a strong position tech wise though and so you now need to ensure that your empire is developed to maintain this good start.
Quite a few contacts.

That makes research/trading easier. It's a huge map though so there are plenty more civs out there though. Maybe a couple of those warriors stationed in your main towns could go out and explore the landmass?
You have a better worker-town ratio than before but most of them are clearing jungle so your productive towns are working tiles that are not fully developed. Sorry, but you still need more workers! I thought that a detailed look at each town would help illustrate this so here goes:
London is working two unmined bgs. If you are serious about that GLH build; surely you want to get it done as soon as possible?
Nottingham is working two unmined/unroaded bgs. (Switch one of them to the roaded bg that you have a worker mining.) You do at least have a worker here though!
York is working fully developed tiles but there is an undeveloped bg when you have roaded and mined a standard grass.
Canterbury is working two hills (as there is no jungle cleared). Neither is mined and one is not roaded. It is not connected to the capital and so corruption wil be higher yet you have a precious worker mining a golden mountain that this town will never be able to work until you get some food there and yes, that means clearing the jungle. Maybe a granary is not the best build here when you have so many tiles to develop.
The situation in Hastings is very similar to Canterbury. Oh, and why do you need a temple here?
Coventry. Please tell me that you are going to build a worker here after those walls are done.
Warwick. Very brave building it under a volcano! I hope that it doesn't erupt. Now why don't you build a worker here? It can then develop those tiles and chop that forest that will then help the temple build. BTW notice that if you move the citizen from the bg onto the fish, you get more income but no loss of shields.
Have you ever heard of the term
wonder addiction? Wonders are nice but the game is won by having plenty of powerful cities. That means settlers and workers.
I see that you are also addicted to spears and that nothing I can say will change that at the moment. You also ask whether Republic or Monarchy is better. Well the answer in almost every situation is Republic but you will not be able to get it to work until you learn to play the game without insisting on having a couple of spears in every town so for now I suggest you go for Monarchy.
