Terribly confused as to what to install and how to go about it

[Captain Trek]

Install the 1.2 fixes from the sticky in the bug and tech sub-forum

If so, I download and install the "Missing sprites", the "Missing general recruitment" and the "Script fixes" files, correct?

Use the unofficial EB Alex mini-mod in the sub-mod sub-forum

If so, I should be downloading and installing only the file that is listed just below where the OP says, "USE THEM ONLY TO PLAY VANILLA EB WITH ALX.exe" (as the others actually modify the game, and I just want to play regular EB with Alex.exe), correct?

Have I got all that right?
