Certs give you an edge, dont do A+ unless you want to just learn the material to learn the material.
If you've ever built a system from scratch you should have more than enough knowledge to handle a help desk job, although the anon that posted about knowing ticket systems and SLAs is right...
I would advise you to pickup something like ccent/ccna and maybe a linux cert like rhcsa or w/e then go to AWS. Networking is nice but the companies that pay good salary for low levels of work are moving to the cloud and because most people know dick-all about it, its a great place to start so you can bs with the best of them.
or you could get into CYBAR SEKURIDY and be a securitard-amazing pay and have the ability to tell the 'nix admins what to do even though you don't know how to cut and paste!
