Hi LD,
Only three sites needed:
First: everymac.com will allow you to identify how much RAM you can fit, and other details about your MacBook model
Second: go to crucial.com/uk to find out the price of RAM and SSDs
Thirdly, and most importantly, iFixit.com will give you excellent guides and walkthroughs as to how easy/hard it is to upgrade the RAM and SSD.
How easy this is depends on the model - I put an SSD in the in-laws old intel MB last month and it was incredibly easy (few screws to be undone, nothing tricky). Newer models are somewhat harder.
SSDs make a vast difference to the everyday 'speed' of the system and you need a new drive anyway... adding RAM can help depending on what you are needing to do. Many older MBs take 6Gb which should be plenty.
