A new guy takes the plunge..., Advice welcome! Options

So after a few helpful (IMG:http://www.914world.com/bbs2/html/emoticons/alfred.gif) from members this past week, I've started dealing with the rust on my '75.
I'm sure, as some have said, that this will turn into a complete resto (read: obsession), but I'm starting with the small stuff, and hoping to take what I learn from that into the bigger parts of the project.
I took a bunch of 'before' pictures, which I'll try to post at some point, maybe a blog...
First up, the trunks. Pictures are easier than a full description, so here you go: The red sled...

Thanks guys!

I did try to poke some more, it's really pretty solid, it's just not really pretty. I think I'll grind a bit more on the really rough spot, and then get into mad-scientist mode with the POR products...

The front trunk turned out to be nothing but a really light surface rust. (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)

And then I pulled the seats and the backpad... (IMG:http://www.914world.com/bbs2/html/emoticons/barf.gif)
The drivers side seat bracket mount was rusted through, and it looks like cracks under the passenger side as well.

One other thing, I rad a few threads about having to scrape a bunch of tar and crap off under the carpets, mine appears to be just painted sheet metal. Was that a difference on early vs late models? (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)
