There is a strip of rotting wood between the concrete slabs on my driveway.
It is about 1" wide. Is this a standard lumber item, or would I have to cut
it from something else? Is there anything better than a strip of wood?

Between the driveway and walkway, and between the walkway slabs, there are
half-inch gaps but no wood strips in them. I don't know what is supposed to
be in these gaps, but now they are filled with random junk/dirt and topped
with moss. What is the proper way to stuff these gaps?

Clean out the gaps and apply caulk. The gray stuff specifically for
concrete.

stuff in a foam filler rod first, then fill the rest with the caulk
recommended by Ron. The gap is likely to be too large for just caulk
by itself.

You are looking for "backer rod". Here is an example:

you need to install the appropriate size for the gap(s) you have.

Follow with the proper caulk/sealant like
There are several good manufacturers but these come to mind:
Vulkem
NP1, if the joints are fairly level use SL1 (self leveling)
DowCorning 795 silicone.

You can also fill the joints with pourable rubber sealant like:

I just went to home depot to look. There are at least 3 similar sealants
that says concrete & masonry sealant, and they are all gray color. Here
they are (I had to use acehardware's web site because HD's web site sucks):
http://www.acehardware.com/search/in...rete%20sealant
Which one do I choose? I want to pick the best one for the job so I won't
have to do it again for a long time.

The driveway is sloped; I probably don't want self leveling. The rubber
sealant looks good but I don't want jet black sealant. It would be too loud
against a medium gray driveway.

One more question: can any of these sealant withstand driveway being
pressure-washed?

Of the names that you show, I would go with the PL product only
because their adhesives are pretty good.

Professional names in the type products I would recommend:
Sika
Sonneborn/DeGussa
Vulkem
Tremco
Pecora
Dow Corning (the only silicone I would consider)

Here is a fairly comprehensive list of manufacturers"
