The different meanings/significance of de的?

In my very few months learning Chinese, I've seen 的 used in numerous situations. In my grammar book it lists the following uses of 的:

• Possessive pronouns
• The "是shi... 的de..." structure
• As a relative pronoun
• Highlighting the noun
• To separate adjectives of more than one character
• Expressing location
• The "自己ziji + 的de" structure (my own, your own)

As a Newbie, how many of these should I be familiar with? I've been studying for 5 months, if that's any guidance. I'm only familiar with the possessive pronoun use at the moment. Perhaps 的 could be a future Qing Wen topic? I've noticed there's been a Qing Wen on The 是...的 (Shì...de) Pattern but I can't find any others for now...
