What Maintenance to do? Parts list included - TB,WP,Coolant Hoses, Fuel Pump, etc

[acura_NA2]

Recently acquired a 1992 NSX 5spd with 69k miles (http://www.nsxprime.com/forum/showthread.php/179349-The-one-that-*almost*-got-away)
The car has some deferred maintenance that I know needs to get done. But after reading and researching posts for a while on prime, I think I've gotten paranoid to the point of replacing things before they break. Labor will likely be done at an independent NSX mechanic.
According to my PPI, here's what for sure needs to get done to make the car mechanically sound (#'s 1 and 2):

1. TB/WP:

(1) 14400-PR7-A01 BELT, TIMING (UNITTA)

(1) 19200-PR7-305 SET, WATER PUMP ASSY.

(1) 90401-634-000 RUBBER, TIMING BELT ADJUSTER

(1) 14510-PR7-A01 ADJUSTER, TIMING BELT

(1) 14516-PR7-A00 SPRING, TIMING BELT ADJUSTER

(1) 90016-P0G-A00 BOLT, SPECIAL TIMING BELT ADJUSTER

(2) 90471-580-000 GASKET (8MM)

2. Cam Plugs

(4) 12513-PR7-A00 RUBBER, HEAD COVER SEAL (cam plugs)


I was also thinking at the same time:
3. All other rubber Gaskets:

(2) 12030-PR7-010 GASKET SET, HEAD COVER (6washers, 3spark plug seals, 1gasket)

(2) 36172-PR3-005 FILTER ASSY., SOLENOID

(2) 15825-PR3-005 FILTER ASSY., SPOOL VALVE

(1) 91318-PY3-000 GASKET, OIL PUMP

(1) 11251-PH7-000 GASKET, OIL PAN

(4) 91213-PR7-A01 OIL SEAL (29X43X8) (cam seals)

(3) 91302-GE0-000 O-RING (8.8X1.9) (cyl head dowels, dipstick o-ring)

Would you do all of the above, knowing that only the cam seals are weeping and TB is over due because of time? Or should I wait? Is there significant savings to labor to have the items 3-7 replaced at the same time?

Sorry for the exhaustive list. I've posted it on here to also help people with their search for part numbers. Above listed is for a 1992 NSX 5spd.

Thanks PRIME!

i was paranoid since my 2000 NSX did not have the timing belt done and was 14 years old...it only had 40k miles but I just didn't want to risk it as everyone on this forum will suggest. The belt did look brand new hen it came off, but visual inspection doesn't always tell the whole story. I would get it done ASAP if I was you so you don't have to worry about it. Here is everything i did to save on labor when doing TB:

Replaced water pump
Replaced timing belt
Replaced timing belt tensioner
Replaced AC belt
Replaced 2 valve cover gaskets
Replaced 6 spark plug grommet seals
Changed out 2 gallons of coolant

The previous owner had done the spark plugs.

I highly doubt you need to change the fuel pump. But I would include the following:

1.Ignition switch.
2.Clean Fuel Injectors with RC Engineering.
3.PCV valve.
4.Clutch Master and Slave cylinder.
5.Flush all fluids- Brake,Trans,Oil,
