You can go up to 24GB total - that's 8GB soldered on the motherboard plus up to 16GB in the upgradeable slot.
What type of RAM do I need to buy?

Usually not - RAM upgrades are considered user-serviceable on most laptops. But check your warranty terms to be sure, and be careful not to damage anything during installation.

Depends what you're doing. For heavy multitasking, video editing, or running VMs, absolutely. For basic web browsing and office work, 8GB is probably fine.
