sorry it's taken so long to respond...work, ugh.
I have friends who have done the SW Tour and all of them have told me it is not worth it, especially now that it doesn't include the dessert party. As for the things you have not done:
1 and 2: SWaGFFA and MotFO you can do on your own, under the same sun as the tour people
3. Nothing special other than the lightsaber churros
4 Available to all and since you have the card you can get in faster
As for Trials of the Temple I have not watched any videos from DL so I can't say
Now the tour guides are knowledgeable on extra things, like they will point out the relation between Who Framed Roger Rabbit and George Lucas's ILM and a pretty cool easter egg in the display inside LB, but that's about it. If you have basic knowledge of SW you know the connection with ST and Indiana Jones
I personally wouldn't do it
