Sounds like it's going good. Diplomats running around the wall is business as usual of course.

Magma and pumps:
You don't need the materials to be magma safe.
As long as magma does not flow over the pump, it's fine as long as there's no wood.

About the cheaty things:
Brewing plants to cook for larger food stacks
2x2 meeting square to stat up dwarves
lots of traps
cross-training dwarves on easy to raise stats
quantum stockpiles and atom smashes
Cooking booze shouldn't be allowed, but if it's that or lose the fort, then by all means save the fort. We can swap over to a purely sweet pod/quarry bush farm if you're worried about food.
2x2 meeting square to stat up dwarves has it's own downside (tantrum spiral risk) so it's fine in my book.
Traps are also fine for me. They jam or need resetting anyway.
Cross training is also fine for me. I usually don't bother since it's too much work to do.
Atom smashing shouldn't be used. We have a magma pipe, use it.
Quantum stockpiles... well, if you have too much stuff (eg. goblin clothing) we can just cut a deal with the traders and trade them at serious undervalue.

ImportantAbout the magma moat, if you're serious about making a magma moat, you need to note the door entrance to the moat I made. Wall it off before pouring magma into the moat.
