Okay, I will spend some more time to find the psi gauge. Are there any other useful readings that I should look to check the condition of the engine?

Usually there is no warning before it goes out and you are left stranded. I wouldn't recommend driving it anywhere until you get the pump and thermostat replaced. Mine was an 07 and JUST went out....so we were definitely on borrowed time as it was.
Honestly speaking, first time I heard the radiator fan running full speed was about a month ago. I started researching the issue, did the water-pump test and it was working fine. The radiator fan turns-on at low speed as soon as I turn the heat on, so I've been driving without heat in 10-20F weather I have been driving like a granny since and the limp-mode hasn't showed up yet.
Do you think driving in these conditions can hurt the engine (over-heat etc. etc.)? If someone can please shed some light on this, it would be helpful.
