There are some similarities to the LPC17XX and LPC21XX series, however keep in mind they are different architectures, you might find the following guide helpful:

Download the KEIL MDK-ARM evaluation version and study the example codes included in the installation.
Learning any ARM architecture can be a challenge, especially if your experience with microcontrollers is limited.
I am using STM32F103 to do some programming and I bought the development board form a chinese on-site shop :www.taobao.com be you can try to find some useful info from some shopping website such as Amazon or Ebay.
I think it is very challenging to develop a board at the beginning,so referencing the other source is a shortcut
@ud23: the thing is i have already got a board with just UART0 a 16x2 LCD and programming through flash magic would mbed still be handy.
@bigdogguru: ill try to get a copy of The Definitive Guide to the ARM Cortex-M3 from a library... the cost is almost prohibitive
I get it that i can go ahead with cortex directly without studying arm7
