O2 bungs are pretty standard. I think it's something like 18mm x 1.5 thread pitch. I briefly had an Area P with a pre-welded bung and it fit just perfect, so no problems anticipated there.
As far as the how-to for tuning, I've used the following threads as my main resource. Some are long, but they're very educational reading. In one of 'em, you'll even see me asking the exact same questions you just did

Like Dan said, bungs are cheap and usually so is getting them installed (I just called around to local muffler shops). I'm pretty sure that stick-thing is a long skinny probe. This is designed for semi-permanent installation with the bung. One could just tie the sensor to a metal stick, but the problem with these sensors and our exhaust is that we've got a ~1.5" diameter exhaust tube (before the muffler). Sticking the whole frickin' probe down there more than little (which ya need to do to get accurate data) a will block a very large proportion of the exhaust gas, leaving back pressure in the pipe (making it marginally harder for the engine to do what it needs to) and distorting the data. The bung allows just the tip of the sensor to stick into the tube, getting good data from just behind the Y-pipe junction without blocking gas flow.

We should maybe set up a sticky or forum in the f/s section (?) to allow us to post up things that we are willing to lend out. Part/tools for borrow?

This forum seems like it's pretty tight knit so it may work out.
We've had certain tools be passed around in the past, like the hard-to-find and only needed once #70 drill bit for drilling carb slides. Think we eventually lost track of 'em, but they're only a few $.

I'd be happy to extend this rental offer to any established users on the forum. But I agree maybe setting up a special subforum group for this kind of thing may be a good call. For me, this is an experiment and I'd rather my tools get some use than just sit in my closet. Mostly asking for funds to guarantee it comes back and repair/replace parts on this if/when they break.

And Alex, for the record, I won't hold you or the forum as a whole responsible if this goes sour
