Update my Trek '82 412

So this is my first inquiry posting.
I have an '81/'82 Trek 412 56cm Roadie w/ SunTour/Sakae 6spd Freewheel etc. DT shifters.
The 6spd Freewheel is rusty and Seized such that it won't freewheel. The Chains rusty. Everything works.

I'd love to update to an Ergo or Sti set up and I'd also like to add some more climbing options.
I've just read about the Shimano Mega 7 and I'd love to know if this would be an easy upgrade and if it makes sense, then where can I get one.

I"m also curious about adding a Triple up front.

All this doable? Am I crazy? Will the Ergo or STI work w/the Triple and the Mega 7?
Will I also need to swap derailleurs?

My other option is to keep the current brake set up and just add bar ends

What will be my greatest challenges?
Will I wind up spending as much as a more modern ride?

The 412 is Trek's lowest level road bike for that year, and list price was under $400. If you really like the bike, then some upgrade is worth it. If it were mine, I would go with bar end shifters. It's a fairly inexpensive upgrade for the price of shifters, cables and DT cable stops. I have some bar ends on my converted MTB. Not as convenient and fast as the brifters on my newer road bike, but just fine for it's intended purpose. If you want to go integrated, then everything has to be matched and compatible, so you would probably be looking at replacing all the drivetrain components.

There is a thread somewhere in the forum where people have posted pics of their classic rides updated with brifters. I'm sure there is also some useful discussion.

Another option could be Retroshift. This system puts your existing DT levers on the brakes.

That Retroshift is interesting, although I think I would try and route the cables differently than they do.
