You can wait on the valve springs. Everything else sounds good.

How many miles are on your car? At some point you will want to change the timing gears and chain unless it has been done.

Valve springs are not bad with the tool some of the vendors have. You have to pack rags around them though to avoid the keepers falling into the engine. Back by the air conditioning box is the tough spot. Feed a long nylon rope in the spark plug hole and bring that piston to the top and it will hold them up no problem. You can rotate the engine with the nut on the alternator when all the spark plugs are removed.

Yes i know the procedure,battery doesnt hold the volts so i have to use charger

A shitty battery in combination with a shitty charging system could cause problems like that. My 87 ran like crap until I finally put a good battery in and stopped jumping it every time I wanted to drive it.

Also, a high idle for a few seconds on cold start is normal for these cars. It's only odd if it stays high for a while.
