I believe you need a 16 mm wrench. It would be better to use a flair wrench to prevent stripping the fitting. In addition, sometimes the fitting is stuck to the fitting in the Power Steering pump. Loosening one will cause the other to turn also. Try using a product like liquid wrench and leave the power steering pump connected (i.e. three bolts in place) when removing the line. Another option is to disconnect the line where it meets the line to the rack by the firewall. You will need a 16 mm and a 19 mm for these connections. Good luck. Hope this helps.
T-60
No..maybe a oil filter wrench to remove it, but, install it by hand (HAND TIGHT)
3/8"
I believe that is a 3/8 Allen key.
Does it have airbags ? If not the centre of the steering wheel will have a removable badge or logo, remove this and you will see a nut that needs to be loosened with a wrench/socket

Using a 15mm wrench, turn the bolt in the center of the idler pulley clockwise to relieve tension and remove the belt.
18mm
My 2003 Cavalier uses a 3/8 hex key. It probably should be the same.
To remove the steering wheel in a 1988 Chevy Celebrity standard version: !. Remove the screws that hold the horn pad in place then remove it. Unplug the wire at the connector. 2, If it still has the safety clip remove it. 3, Use the appropriate wrench to remove the nut from the steering shaft. 4. Use a steering wheel puller to loosen then remove the steering wheel. Reverse the instructions to replace the steering wheel. Steering wheel retainer nut should be 30 ft. lbs. torque.
May only be able to fit in an open end wrench.
You need a 10mm wrench.
