Hacking Understanding 'factory firmware'

[aaqi]

Hi, I'm sorry if this has already been asked but I've had a look and can't find the answer I wanted.

I'm looking at buying a PS Vita PCH2016 and obviously want to use homebrew, from the research I've done it's recommended that I use the 3.60 FW and after looking through the guides if the factory firmware is above 3.60 I cannot downgrade to 3.60. (unless I'm interpreting this wrong and just have to gradually downgrade through the FW)

Is this really that big of an issue? Could I still download and play games (including PSP games) with a higher firmware, if not how can I check the 'factory firmware'?
The PS Vita I'm looking at currently is factory reset and on 3.73 FW. Does this mean that the factory firmware is 3.73?

Sorry for long question and thanks in advance
