size e.g. 2 x 256mb memory or can i have two different e.g. 1 x 256mb and 1 x 512mb memory.

This is not mandatory to be same. You can use different size of RAM in different slot. But performance will be better if both RAM is of same BUS speed.

well it depends on the type of memory set up you already have if it has two open slots it can probably except DDR2 or 2 x 256 as you said. It can probably accept DDR 1 x 256 and 1 x 512.
DDR2 is faster and usually more reliable
to check out what you actually have go to http://www.crucial.com/systemscanner/
and click scan my system it will tell you what you system can accept and the configurations

It will work if you have two of different sizes however the larger one will only run at the same speed as the smaller one.
Eg. if you have a 256 mb chip and a 512 chip, they both will only run at 256 mb's each.

They don't have to be the same size nor it is recommended. They don't have to be the same make either. The most important is that if your laptop can fit DDR2, both have to be DDR2.
You can therefore fit 1Gb and 256Mb it's your choice.

check the documentation from the manufacturer. some systems have to use the same manufacturer and type for each memory module. pairing can also add a slight performance increase.

Best way by far is to go the crucial.com route as already mentioned. They will give you a run-down (free) on your specific machine and make recommendations about upgrading your RAM

they dont have to be the same size, but it is recommended that they be the same brand and same size.
(i havent had trouble with memory that is different sizes or brands but thats just what is recommended by computer companies)

simple answer yes if those individual chips are suitable for the machine, and not in conflict with each other
