@ OP. There are a large number of posts regarding the nRF24XX and nRF24LXX devices. My recommendation is to read them all. Search this website as well as Google nRF24L00''s for whatever you find. it's a bit of reading but in almost every post or article I've found more and useful data.
Maniacbug's library is well done and easy to use, I recommend it highly.
