Now, this is quite a large topic to ask about, as I find that the names and the races are interlinked (obviously), so I will just talk about what I know about.
Which goes best with the Engineer?
This is simple, the Charr and the Asura. The Charr pretty much invented the Engineers and their mechanisms. The Asura because of their natural ingenuity means they would be able to create wonderous devices quite easily. Humans fit most roles easily, but have no specific niche for a profession, and so are viable for them all. The Norn, they can be engineers, but I don't imagine it appealing much to them, as it would seem less heroic them hitting someone with a greatsword or suchlike (unless using the Tool Kit, then they charge in with a wrench). Sylvari seem the least likely to be engineers, due to how close they seem to nature, and seem directly in contrast with the Charr's industrial nature which suits the engineer so well. A Sylvari could pull off being an Engineer though by saying their instinctive curiosity for the world makes them want to learn how everything works (maybe).
Which race/gender do you prefer?
Personally, it is the Sylvari who are the best. I love the idea of how attuned to nature they are (they are plants, so that point is obvious), and their naiveity. They just really appeal to me. But as discussed, they do not suit the role of engineer very well as a race. I also play a male in any game.
Engineer Names?
Now, this is a topic I find quite hard, as I feel a need to keep the names RP-worthy, even though I dont RP. But I will still give it a shot:
Charr:
Second names are the inventive parts here, so for first names, check out the
Naming thread here
Darkcog
Quickgear
Fiercewrench
Keenmind (an in game NPC)
Asura:
Asura tend to have short names with double constanants, but I can't think of a way to turn it engineer-y, so my suggestions are generic asura names.
Zigg
Tribbur
Krash
Blipp
Human:
Human names are once again generic, but you can have fun with the surnames, and can even make them titles such as:
the Tinkerer
the Inventer
Norn and Sylvari
I am sorry but I cannot think of any suitable names that aren't mentioned in the naming resources linked before.
I hope this helps a bit!!
