Yes. The file may be jerky if it more than 2-3 per hour.

I assume the ideal is zero dropped frames but how often is this achieveable and does this even mean the capture is good?

I almost never get dropped frames.
It may be the computer, the audio card, the capture card, the software, or the competing running programs pulling on the CPU.
I need to know more about the system to guess/troubleshoot.

Is there a point during a capture that the number of dropped frames makes it pointless to continue?

I stop mine if it's more than 2-3, or if it isn't dropping because of an obvious bad spot on the tape. I have a stack of tape hat I'm just going to redo next week. Had to rebuild the computer. It started to drop frames after many years of use. The CPU was toast, I think, so into the trash it went.

Is it feasible to capture "blind" return after and hour or two and make a judgement

I check every 10-15 minutes.

Finally is there anything that must be done at the capture stage, assuming the recommended settings from the site guides are applied (for say mpeg2), that can't be corrected later in software?

Depends on what it is. Some yes, some no.

A few frames won;t really affect it. ATI MMC drops audio with video, so there won't be skew. (Assuming that the card in use. Not sure. I'm guessing.)
VirtualDub will skew.
