The text below show problem identifying my MacBook model by S/N. I hoped to add more RAM (currently 2 GB 667 Mhz DDR2 SDRAM) to 8GB. Would be great to replace current HD (160 GB SATA Disk) with at least 500GB.
Can I do either or both? Not averse to visit to Apple Store for work.

Determine your MacBook Pro by serial number
On most computers with Mac OS X, you can find the serial number in the About This Mac window. Otherwise, see MacBook Pro: How to find the serial number to learn where to find the serial number on the surface of your computer. When you have the serial number from your computer, there are multiple way to determine your product model.
Option 1: Type the serial number into the Check Your Service and Support Coverage page. The resulting screen will show your model, as below.
