Welcome! Here are the website rules, as well as some tips for using this forum.
I want to move over my water meter, backflow preventer, and expansion tank. I'd like to move them over to the right a little closer to the gas meters. I want to upgrade the size of all of them as well. They are all 1/2 inch, and the pipe coming into the house is 1 inch. I'll be replacing the rest of the plumbing in the basement with at least 3/4 inch since it's a mess.
Is there anything I should know about touching the backflow preventer and the expansion tank? I want to put the expansion tank vertical also.
Anyone think the Water Dept will bust my chops?
Any tips greatly appreciated.

I would show them the pictures and explain that you would like to make it better and see what they say.

Be careful with the electrical grounding. That has to go back together clean and tight.
One note of caution, If their are any loose neutral connections in your electrical system or in any of your neighbors systems this could cause power to flow through the bare ground wire and your water pipe. Best thing is check the water pipe and the bare ground wire with an ammeter before disconnecting any ground wires

There are two considerations for BFDs on a building, one is to protect the public system from any reverse flow from your building, a water main break, hydrant draw, etc.
A second BFD requirement protects any equipment inside your building from contaminating your water within the building. This type of BFD is usually installed at the equipment, soda dispensers, coffee machines, commercial laundry, etc really any connection that could cause low or high hazard conditions within the building.
Be sure whoever you spoke with is clear on what you are removing.
Many public water providers get funding from State or Federal programs and BFDs are one of the requirements for those programs. Plumbing codes also dictate BFD requirements.
More and more water authorities are requiring yearly testing and certification on that type of BFD. If it has test ports, it needs to be tested.

Even though they have to be bonded together, you can't use the gas line as electrical ground for the house ( think this just means you need to ground via water pipe and/or ground rods)

The BFP was installed as you mention for Medical use in the building. If this is being discontinued, It will probably need to have an inspection done to cover that and verify the removal and the reason for that removal.
Keep the expansion tank in place if you find that incoming water fluctuates. This can cause relief valves to prematurely discharge and close.
Its' a good that you are improving your water main. A shut off valve on the meter spud on the supply side of the water meter might be required as a up date to your system.
Also expect the water company to want to replace the water meter.
