In general, you'll find it a reasonably big jump moving to ARM from 
something like AVR. There's more to set up and fiddle with and learn, 
but then you're going to get to learn about a powerful CPU 
architecture that will be useful for a good while.

You can't add more memory to an LPC2106 since the bus is not exposed.

For the most part, working with the LPC2106's peripherals will be much 
like anything else you've worked with. One thing to watch out for 
though is that the GPIO pins on the LPCxxx are slow. With a 60MHz CPU 
you can't generate more than approx 3MHz square wave out of a pin by 
pin toggling because the GPIO peripheral is very slow.

Hope that helps a bit.
