Maximum RAM that can be installed on that machine is 3GB, so all you need is one 2GB stick and you are done.
I get mine from Crucial.com but Ramjet is an alternative. Both have a Configurator that will step you through the process of finding the correct RAM for your machine. Their RAM is warrantied for life. RAM is cheap.
On the other hand, OS X 10.5 is not cheap! You will find it on eBay or Amazon ranging from $99 to $159 for the retail OS X installation disc. It is black, avoid the Grey ones.
Alternatively, your machine can support up to 10.7.5 but I think it would not have the legs to carry this off nicely. 10.6 (Snow Leopard) on the other hand may be ideal.
Snow Leopard is available for less than $30 on eBay.
While SL was designed as an upgrade from Leopard, it contains a full installer and many people have gone straight from 10.4.11 to 10.6, skipping 10.5 completely.
For $30 it is worth a try
