To save board space and maybe a few pennies on the connector, I've seen something called Tag Connect.  This is a 6 pin pogo connector that attaches onto the board and makes contact with the traces.  That might also solve the space problem.  When I used it on a PIC based project it worked well.

Yes, I believe that is correct, RESET is not needed for debugging, only
programming.

Actually, that may be true. I currently have the JTAGICE MkII connected to a
device using only the six pins I mentioned. That is sufficient for JTAG
debugging but it may not be sufficient for programming.

Either way, using a finer pitch header and an adapter may solve the space
issue.
