The first thing that has to be done here is to have the fault codes checked using a fully compatible scan tool that will plug in and can read all computers in your model to see what codes are set in the suspension computer.There will be at least one code set to help locate this fault.This could have been an issue with the compressor itself stuck on ( compressor failure is common ) or a faulty with a level sensor sending a false signal.If you can get me the code info this will help me to help you try and pinpoint this issue here just let me know.

Yes,there is an exhaust valve.The valve is part of the compressor assembly.Most likely it was not allowing the exhaust valve to open to allow air pressure bleed off.
I would repair the wires if you can or parts warranty the pump you purchased from the facility you got it from for another one at no charge to you and replace the damaged shocks.Then you will need to have a scan tool that can communicate with the air suspension computer used to clear codes from this computer.The suspension system will not operate properly until the codes are cleared out.This is a higher end scan tool usually a parts store wont have but you can check with them.This is usually a scan tool that is $1000 or more to purchase as usually the cheaper scan tools will only communicate with the engine and brake computers.I can send you a link to a scan tool to purchase that would work but keep in mind it is near $1000.

Arnott shocks are good shocks and some claim they are better then factory.I would go with the Arnott or factory to be safe.The safest shock is factory as it is specifically designed for your model where in some cases the Arnott may be designed for more then one model.But you can go either way with these here.Monroe shocks are good as well.
