Worth Fixing?

Here's the list of issues that mostly need attention and are serious.
Do you think this car's worth fixing? Secondly, how much do you think
it would cost to fix all of this? (1988 Pontiac 6000 2.5 with 125k
miles - throttle body injected) The ones below with asterisks (*) are
not serious.

1. Stalls especially when you goose the gas pedal from a stop from time
to time, especially in reverse and especially when the steering wheel is
turned sharp. It will do it going straight however. Sometimes turns
over bad on the restart after it stalls. It didn't actually used to
have a problem starting back up until the past few months.
2. Has issues starting below 0 (F) and the battery appears to be good.
(Turns over very slow - if the motor does start, it sometimes sputters
and dies after a second or two on the bitter cold days) Oil used is
5W30 and was changed less than two months ago. It also backfires
sometimes when you're trying to get it to start on those bitter cold
days like today for example. You could actually see the smoke coming
off of the engine when it backfires back by the air filter some place.
3. Putt-putts like a lawn mower does.
4. Misses really bad especially if you begin to drive the vehicle and
don't let it warm up for at least five minutes on days where the
temperatures are below 50 (F). It really misses when you come to a stop
when it's still cold.
5. Misses and sometimes dies when you give the car gas when you first
start it up cold even if you just lightly press the gas pedal.
6. From time to time, it turns over poorly if you start it up hot.
*7. Cruise control does not work.
8. Valve cover gasket leaking. (PCV valve possibly causing this as it
has been addressed several times before)
9. Dad says he can hear the engine making a knocking noise.
10. Possible engine rocker noise heard on occasion when started cold on
colder days.
11. Timing may be off - not sure.
12. On occasion, a "rotten egg" smell is noticed when driving the car.
Seems to do this more on colder days and seems to be infrequent. It
only does this once a month at the most and it appears to be random when
it does this and when it doesn't.
13. Tapping noise heard from the engine. (I've noticed it slightly and
Dad has also noticed it.)
14. Sometimes acts like you're not letting the car turn over long
enough. (This is where I think the timing may be off.)
*15. The A/C does not work and will cost more than it's worth to fix
from what we've been told.
*16. A speaker cuts out at low volumes - when you crank the volume up,
the speaker kicks back in.

In a previous post done by me earlier today, I discovered the antifreeze
leak was just caused my a hose that was not tight. I tightened it up.
We have tightened up that hose before, so for some reason, it keeps
getting loose and has be tightened from time to time I guess.

I just checked my oil level today and it's fine and the oil's condition
also looks fine.

I stopped reading there. The answer is no. A 19 year old dime-a-dozen
sedan that has a LIST of issues? No No No. Not unless the educational
value of doing the work yourself comes into the equation, but even then
I say no because all the technology in that car is waaayyyyy outdated.
