First I buyed a development board from a brazilian vendor called Elaxys 
(www.elaxys.com.br), I am using the EX_LPC_M01 wich is just nice, and cheap 
(for brazilian prices, our import taxes are simply abusive and a board 
assembled here become much more cheaper). With that board I made a few 
firmwares, and the board comes with a CDROM that contains tha gnuarm ready to 
use in Linux and Windows (of course, I use Linux), a lot of libraries made by 
Elaxys wich is MIT licensed (as seen on 
http://www.elaxys.com.br/produtos/lpc/ex-lpc-lib1/ but unfortunatelly only in 
portuguese) wich have nice functions, like one to made an routine a ISR (I 
cound not find how to do it in gnuarm alone, I can only made an ISR with 
these libraries), I buyed an Wiggler JTAG and comes in the CD too a program 
to connect GDB to the paralell port (the program is called exmon and can be 
downloaded from the Elaxys site). 
With that baord I tested the ISP program from Philips, and lpc2isp. Then I 
designed my own board, uploaded some firmwares and I am testing right now.
It is now really nice to develop im my board, because I made an ISP header 
that have an ON-OFF switch to power the entirelly board, and another switch 
that puts P0.14 low. And a DB9 caonnector to connect to the computer serial 
port. So, When I power the board with the ISP switch on, I load the firmware. 
Then I power off, turn the ISP switch off, turn the board on and the firmware 
runs, very nice. 
I developed a lot with PIC microcontrollers, using Microchip ICSP but I 
allways had to plug and unplug the ISCP connector, the ISP is just great.
Ah! another neat feature, I use UART1 in my system, and I use UART0 as a 
debug-out (I send bytes like opcodes to show me what the firmware is doing) 
so I use the same serial connection to read these caracters in minicom. 
Really nice...
