So the semi-antique coffee table I picked up on eBay has wobbly legs.
The table seems well-constructed but the little wooden triangular prism
leg-bracing blocks were all either cracked in two, or the glue had
separated from one face of the block or the other.

I've knocked them all off and cleaned up the residual glue from the
legs. Since I'm more of a machinist than I am a woodworker, I'm tempted
to replace them with some little pieces of lightweight aluminum angle
and some small screws. Any reason not to do that, other than purity?

If I go wood, does it matter what type of wood I use, and what type of
glue?

A photo would help a lot. One primary concern would be whether the
screw holes on the table have been stripped to the point there isn't
sufficient room for another. In my antique collecting days, I ran
across furniture that had been mended with mending plats or the new,
cheap, angles - never very strong. If the blocks are cracked, cut
another from some sort of close-grained wood, with grain horiz. to make
the joint strong as possible. Removing old glue probably isn't critical,
but smoothe, flush fit is. Elmer's Wood Glue is good. My hubby
recently repaired the plank seat of an imitation antique wood office
chair, using Gorilla Wood Glue, which is holding (he is a big, heavy
guy). Gorilla sets up fast, and requires clamping for ?24 hrs, but I am
surprised that it is holding - plank seats are tough to glue.
