Download links version queries

Hi,
Fairly new to Pro tools and I am in the process of downloading (I have also recently registered an Eleven Rack) and have some questions related to what I have available to download.

I am planning on running PT11 and the downloads I have available are as follows (I have only included win):

Pro Tools 12.3.1 T (Win) 1.37 GB
Pro Tools 12.3 Installer (Win) 1.37 GB
AIR Instruments Bundle 12.0 Installer (Win) 1.25 GB
AIR Effects Bundle 12.0 Installer (Win) 98.12 MB
Xpand II 12.0 (Win) 1.23 GB
Codecs LE 2.5.1 Installer (Win) 7.24 MB
DX Driver 5.9.0 Installer (Win) 1.42 MB
Pro Tools 11.3.2 Installer (Win) 1.09 GB
AIR Creative Collection Instruments 11.3.1 Installer (Win) 2.47 GB
AIR Creative Collection Effects 11.3.1 Installer (Win) 98.12 MB
Pro Tools 10.3.10 Installer (Win) 1.77 GB
Avid Virtual Instruments 10.0 Installer for Pro Tools 10.x (Win) 2.53 GB
Pro Tools Demo Session (Mac/Win) 286.34 MB

Of these, which can i use with PT11?
What is the difference between PT12 and PT12 T (in the event I upgrade in the future)?

I also have additional content as follows:

Eleven 12.1 (Win) 31.5 MB

Tri-Knob Fuzz 12.0 (Win) 3.27 MB

Are these only compatible with PT12?
