I have an Olimex LPC-L2294 board myself, among with a couple of other boards.
I have some years of experience doing microcontroller applications on
8 bit micros (Motorola, 8051 and PIC) but I still had a few problems
getting started on the ARM because it is very different to the 8 bit micros.
About documentation, I've found the board schematics to answer most
questions
that are specific to the Olimex board, although they should publish an errata
as I do know there are at least a couple of confusing things on the E2294 board.
The documentation I really use is the chip's user manual and I sometimes
peek
at the ARM instruction set guide for debugging purposes.
As for example code, I've found there to be plenty around,
and even if it's written for a different LPC2000 series chip it usually
will run without any major modifications on another chip as long as it
has all the peripherals used in the code.
I've found this web site to have some good examples for the GNUARM
toolkit:

Try downloading the GPIO example to start with, it should work on your board
if you just change the definitions of where the buttons and LEDs are
connected.
Use the Philips LPC2000 flash utility to upload the hex file once you have
compiled the code. Be sure to remove the bootloader jumper after flashing
as otherwise the bootloader can't exit (I ran into this myself, being used
to
the Motorola bootloaders which allow you to exit from the bootloader if
needed)
