Yeah basically if you just go with 3 heavy bolters on your tanks, you'll be paying less and getting more effectiveness out of them against anyone, not just orks.

The four flamer command squad is kind of a hit or miss thing here. I'd rather just take a heavy bolter or something. Same with the power weapon. It's tough to lay wounds down with a Str 3 model. The shootier a guard army is the better, and for a JO a storm bolter could be a good choice here instead, should you choose to go that way.

You may want to pay the points and make your melta stormies deepstrike, just so they get a better chance of hitting some high value targets early. If you don't want to do that, you could change it to a Veteran squad, take more melta and deepstrike them. Either way, meltas are tough to get into action without using deepstrike or infiltrate.
