You can right click on the files you want to rename and choose Library Tools->Rename Files From Properties...
Then set your folder location as you want. You can even use tag info to build the folders. For instance, for audio I typically set the base path to My Music\Albums, then I set the Directory Rule to [Album Artist (auto)]\[Album]. Then I set the Filename rule to [Artist] - [Name].
For the filename you want to construct, you could use [Series] - [Season] - [Episode] - [Name] as your filename rule.
In the example you show below, that would result in: The War at home - 1 - 13 - Unknown Name
If you want the brackets like you show there, then you'd use [[Series]] - [[Season]] - [[Episode]] - [[Name]] and you'd get: [The War at home] - [1] - [13] - [Unknown Name]
If you want to eliminate the "Unknown Name" (or Unknown Series, season, etc), then you can probably use an expression, but that's a lot more complicate and I don't know too much about it. There are others on here that are absolute wizards with expressions, though.
