I've done LPC2194 and LPC2294 designs and just do the stuff you should do
on every design:

Keep the xtal close to the uC and on the same layer as the uC.
Put a .1 or .01 uF cap on EACH power pin.
Put a 10uF or two tant. cap on the board.
Keep the power traces short as possible.
Study the LPC2xxx user manual for any pins that need pulled up or down.

Keil has a schematic for their eval board online:

Get some ideals there.
Good luck!!!
