Will running my car without the under-engine tray make my car run hot ?

Do you need to bleed coolant sys several times before it will be completely bled ?
Coolant/radiator hoses are spongey and not stiff after the car has completely cooled down, ( but when its running and all warmed up it has plenty of pressure).
Also seems like the coolant level goes down a little bit too after car shut off and is completely cooled down(from coolant going into the overflow), is this normal ?

Only if you don't do it right the first time.
That's normal.
Yes, that's what the overflow bottle is there for. Water expands when it gets hot and contracts when it cools.

what the proper way to bleed it ?
i filled it up on the radiator with the bleeder screw out until rad was full then put that cap on and put the bleeder screw in, then i filled the other spot at the filler neck until full and ran the car with the cap off and until it was warm then put the cap on and let it keep running until warmed up and then i shut the car off and bled it with the bleeder screw letting the air hiss out until just water dribbled out
is this the right way or no ?
edit - Also my exhaust manifold does not have the heatshield on it , will this cause my temps to rise on the coolant ?
