If im not using any pins on a IO Bank do i need to connect up its IO VCC? or can i leave this bank completely un powered? Regards Russell Pirie

but it would be nice to add a JTAG header to that system as well so i can quickly test new designs, and only use the boot off the micro controller once im happy and the board works standalone

Yes, so you have already answered the question yourself.

can the two be combined? i had a quick read of the AN 250 doc but could not find any examples of boot from micro controller combined with JTAG or AS header

JTAG configuration and debugging functions are available in any configuration mode. AS mode is alternative to PS. You need switches or jumpers for MSEL to select between both.
