I'd strongly recommend Team Member+ to anyone who wants this game - The game develops VERY fast and sometimes a month feels like a long time to get the updates! If you want to be on the cutting edge with all the major updates it's a great investment. This also gives you access to the Highway Tracks which aren't Junior accessible yet.
You can buy Junior and then upgrade to Team Member for the difference in cost if you'd like to check the game out first too.
The DX11 garage bug is caused by Anti Aliasing. Turn that off and it's solved, but it only affects the garage view, in game is fine, so it's not worth turning it off just for that IMO!
Most FFB settings are usually for the steering wheel driver settings (Logitech/Thrustmaster/Fanatec etc software) You also have the F1 key which brings up the developer panel, there are some FFB tweaking tools in there too, but they do not save, they're just for testing.
