Yes, you can program the Flash through the JTAG port, but it won't be
fast and it will be a bit of work to get production quality software
running (meaning "push this button to program").  

IIRC, all of the LPC parts come with a serial port boot loader that
should be a bit easier to get running for your needs.  Can you use the
serial port?  If you don't want the RS232 transceiver on your board,
you can use a paddle board for that.  If you don't want the cost of a
connector on the board, you can use a card edge connector or even a
clamp on connector.
