Can any Kanjidamage users help me out?

OK, so, I've just finished learning my kana and want to go onto kanji. Heisig was good but a touch too dull for my liking, so I'm going to try out Kanjidamage.

All I'd like to know is, what exactly do I learn? Just the mnemonic/keyword, or the kunyomi, jukugo, etc.?

It just seems like an overwhelming amount to learn for each one the first time through, and I'd like to know how others who have used it went about it.

Thanks.

I just had a revolution. A lot of the Okurigana that I'm seeing from the Wikipedia explanation of them can be found in earlier gramatical teachings through Tae Kim's Grammar Guide, found here: http://www.guidetojapanese.org/learn/grammar

I forget where exactly in the exercises I saw them, just that I remember seeing them. I think what I plan to do before going into KanjiDamage any further is to go over Tae Kim's Guide and gather better fundamentals on verb and adjective particles. I think this is what might be making it difficult for me when attempting to understand the KUN readings on KanjiDamage.
