There is one formation that gets you free transports, it's the full battle company. The rules are in codex: space marines with the Gladius Strike Force. Basically, if you take two demi-companies, a captain, chaplain and one auxiliary all our Rhinos, Razorbacks, and Pods are free.
The Flameblade is the Salamander specific formation. I've never run it or seen it used, but I've read it. It has a few benefits. You get a master crafted weapon on all your characters. This means you should probably buy something for all your characters, like squad sergeants. Most fluffy would be something like a power weapon. You could also get a combiweapon, meltabombs, or just mastercraft your bolter, I suppose.
Your flamers also get even stronger.
Finally, if you don't move, you're fearless. That's interesting, as it means you can't be pushed off an objective once you're on it.
He'stan in the flameblade is a tough call. You're getting insanely powerful flamers, so I'd be looking really hard at Flamer/Combiflamer in my tactical squads. If you really wanted to max out, something like this:
10 Space Marines, Flamer, Multimelta, Veteran Sergeant, Combiflamer, Powerfist (master crafted for free)
That's a pretty powerful tactical squad; not sure that spending that much a 1W sergeant is worth it, but you're using all your benefits to max effect. Definitely practice your model placement on protecting your Sergeant and look out sirs.
Based on your model list, you could probably make a Flameblade with a battle demicompany and auxillary. Post up a list for critique!
