The methods depend on each person. The ones described above seem quite good (especially the one of writing the 漢字 in hundreds, that is always useful).
Yet there is another way to learn the signs (漢字).
You would doubtless know, brettonataylor1131, that all the Chinese signs are constructed on the basis of roughly speaking 214 basic signs (the so called keys).
So in order to be able to learn the entirety of the signs, you would need to learn the 214 keys and the way they are changed depending on their position in the sign.
It is not unlike learning to count. One does not need memorise all the cyphers from 0 to infinity (which is impossible in the case of the humans), it is sufficient to memorise the digits from 0 to 9 and the rules to organise them in sets and one can generate the above infinity (generative grammars are based on this principle, by and large). The same case is here.
What you need, is a book (site, course) which would dwell on:
(1) History of the key (what forms it had in different periods of the development of the Chinese calligraphy);
(2) Its meaning (present and past - because sometimes the sign means one thing nowadays, but when it was used for the formation of another hieroglyph it had a different meaning, so beware!)
(3) Its use as a constituent component in other signs (what changes it undergoes when used and what is the logic behind the use).
Knowing the history will tell you why the sign has this particular form, knowing the meaning will tell you why the compound signs have such composition, and knowing some of the uses of the key will show you the logic (however weird in some cases of the ancient Chinese, but, after all, the history of Chinese calligraphy is more than five thousand years) behind the signs.
Well, there is a book out there for you, and the reason why I went to the pain of describing the qualities the requisite book should possess is that the book I am talking about has been published in Russian, so if you know a thing or two of the Russian language it would be a great help for you:
