Upgrading black macbook

I have an old black macbook from nearly 5 years ago. 2.0Ghz intel Core 2 Duo, build 10K549. Right now it has a 2GB 667 Mhz DDR2 SDRAM on it. A couple of questions:

1) How much memory can my laptop take? 4GB?

2) Will any DDR2 RAM do? For example, is anything from this list here fine? http://www.newegg.ca/Store/SubCategory.aspx?SubCategory=381&name=Laptop-Memory

3) When purchasing an SSD drive, do I just have to look out for a 2.5" drive from this list? http://www.newegg.ca/Store/SubCategory.aspx?SubCategory=636&name=Internal-SSD
Or are there any other criteria that has to meet my laptop?

Thank you all.

 

Thanks! I got this: http://www.everymac.com/systems/apple/macbook/stats/macbook-core-2-duo-2.0-black-13-specs.html

But I still don't know if I can throw an SSD hard drive in there, and if I can, which ones. I see that I can upgrade the RAM to 4GB, even though around 1GB of it will not be used.
