the oil pump has a metal pipe going to it, theres a filter on it that's probably clogged. doubt they changed that line. tell them to remove it and change or clean it
Just check the filter every couple of months to see if its dirty or needing to be replaced. I recommend you change it every 30,000 miles or more if you drive in dusty conditions.
That light has nothing to do with the level of oil. If it's blinking it means the oil pressure is extremely low and strictly saying car should not be driven. There are couple reasons for that. First one is your oil filter is clogged and has to be replaced. Second is the oil pressure sensor does not read the pressure properly. Third oil pressure release valve went bad. And forth one is your oil pump has to be replaced.

It should probably last about a couple months.
Sometime the fuel pressure leaks down went he engine is turned off for a couple hours or more. If that happens the engine may be difficult to start later. Try turning on the ignition switch for a couple seconds allowing the fuel pump to build a little pressure, THEN crank the engine. See if it makes any difference.
