I can see now why you do not want to call them. Well, if you want to be well prepared and have hard data in hand, instead of opinions, Alldata account is only $40 for five years. That's dollar 8 a year. But it will provide you with all established repair times, that pretty much all shops use. Even some dealerships. Also, very handy for DIY types.
There are many reasons why a timing chain and oil pump may need to be replaced during the normal service life on an engine, but rarely are they an isolated issue. There are associated parts that might need to also be replaced at the same time.
Perhaps the OP can provide further details as to why they are seeking this work; engine history, mileage, service/maintenance details, etc.
Vehicle is in great shape other than 213,000 miles. Might ship it to Costa Rica for a vehicle down there. This vehicle has had mucho dollars spent on it such as total brake overhaul, shocks steering parts all replaced, distributor.(previous owner). Compression on all cyls is 145. And i like it.

Call around to a couple other shops and ask them what the flat rate is for what you need done. That will give you something to work with. Of course the shop that gave you the cheap labor rate might not follow flat rate guidelines.
The shop is owned by a buddy of mine. I used to work on all types of equipment but i don't anymore. I was thinking about 5 hrs labor to do it.
Maybe i should have just asked how many hours to replace the timing chain and gears. When ever i changed one in the past i always replaced the crank and cam gears also.

Timing chains, bicycle chains, mototorcycle chains... they all get longer as they wear, yes. And with sufficient wear, as you said, they may need replacing because they can cause damage if they slip off and break. Or even if they just jump a tooth, altering the relative timing.
What confuses a lot of people about chain wear is that it's commonly called "stretch," when it isn't really stretch at all, but simply effect of the accumulated wear of the individual roller pins and holes in the links. Individually it may be a small dimensional change, but the cumulative total adds up over many links.
Technically you are right. But over time they wear. But most dont replace till a rebuild is needed. Then people go to double roller or timing gears. By the time ( usually) they wear out the motor most likely needs a rebuild anyway. If they break you're gonna need a rebuild. I guess you can be preemptive and replace it.
The oil pressure. Check and make sure the oil pressure sensor isn't bad. I had 95 with 4.3 and the sensor was bad. Read low pressure. It's located on the back of the lifter valley Nader the distributor and its a pita to get to. It helps if you have small fingers.
The oil pump is inside the oil pan. It most likely require pulling the motor. At that point you might as well just put in a reman.
