TMS applies template modifications to compiled templates; the template source is not being modified.
If you use TMS for all your template modifications, it is not necessary to manually edit templates.

Also, after each template edit, are you supposed to export the template edit to use in the future should there be upgrades to the vBulletin software, thus not needing to redo all of your previous template edits?

You do not have to export template edits. This is only necessary if you want to copy template edits to another vBulletin installation or share them with other users.

Also, I noticed that the only style I have on my board is the Default style; I do not see a Master style. Should I have both?

MASTER style is only visible in debug mode, but it is not necessary to turn on debug mode to add template modifications in MASTER style.

Do I need to uninstall these MODs beofre installing TMS or is there something I need to do with them after I install TMS?

Do NOT uninstall these modifications! If you do so, you will loose the data.
However, you can undo the template edits you did manually for those modifications and add them to TMS instead. This is recommended to avoid having to manually update templates on vBulletin upgrades.
