You should just memorize how to write each of the parts. There should only be around 100 or them, and they can be found at the beginning of any dictionary that is used to translate kanjis. It is also useful for looking up meanings of kanjis. Than, you can just memorize what parts each kanji is made out of, instead of memorizing around 5 to 15 lines for most kanjis.
Also, the 2000 kanji number depends on what you need it for. By the end of elementary school, you learn over 1000. Around 1500 is enough to read newspapers, read street signs, read books, and get around every day life, as well as work as a janitor or basically anyone who doesn't work with the brain. If you want to be a secretary, scientist, etc, than you need at least 2000 of them to understand most of the conversation.
