1). Cutting boards
Does anyone know of a suitable mini saw table/inverted router type setup to
accurately cut PCBs to size?<<
There are small "table saws" with 5 or 5½" blades available. Not much good,
but would do for PCB work, but ONLY if you use a carbide-tipped blade. The
more teeth the better.

I know Dremel do a few add-ons for their hand held drills, but are they any
good?<<
Simple, accurate answer: NO.

Is there any other kind of hobby/craft mini-saw table that could do a nice
job of cutting PCBs?<<
And cutting of FR-4 with a NON-carbide blade (i.e., plain HSS) won't do more
than one little board before it's "gone" and needs resharpening. I have
used a disk-sander to "clean up" a board with nuppered edges or slightly-large
dims.

2). Drilling
I can't really see any other way than a Dremel by hand...<<
Then you obviously haven't SEEN much! You will NEVER drill PCB holes with
proper solid-carbide PCB drills with a Dremel. Even with their "drill press
stand" thing, there's little chance!

You MUST use a proper and accurate drill-press. If you can find one of the
little versions at HF (better: Enco, though not much!) with no runout (15%
chance?) that may do if you can hold the board steady on the table.
