1.) On http://www.embeddedartists.com/products/lpcxpresso/lpc1549_xpr.php 'Current consumption can be measured of all target side circuitry'. On page 1 of the schematics P3 are open pins in parallel to a zero ohm resistor. To measure the current I have to cut this resistor and connect my amp-meter between the P3 pins?
2.) On http://www.lpcware.com/LPCXpressoV2Boards, section 'Debugging via the built-in debug probe', 'Debugging an external board using the built-in debug probe' the jumper settings are described. But how to connect (what) wires? Removing the 10-pin header and connect the (at least in my toolbox) unusual 1.27 mm pins with SWD, clock and so on to the external target?

The LPCXpresso1549 has a standard "Cortex 10-pin 0.05" JTAG/SWD Connector" fitted. The same connector is used for both debugging the onboard MCU using an external probe or for using the onboard debug probe to debug an off-board MCU (after configuring jumpers appropriately). Typically, you would have the same connector on the target board you wish to debug, then use a 10-pin cable to connect the two. For more details see:
You can see this being done in the "Rapid Embedded Development with LPCXpresso" video at http://www.lpcware.com/lpcxpresso (starting around 52.45 into the presentation).
