Don't worry too much about EK or AS not being in an alliance. You don't have to fly on AS metal as you're simply using their ff program to credit EK flights to.
If work is paying for EK in J you'll get lounge access anyway based on your class of travel ie access to J Lounges so you don't need to rely on elite staus & the crediting of that number to use the lounge.
Therefore being an entry level member of AS matters not. What problems did you foresee with AS not being a OW member?
When you do start redeeming AS points for travel on CX, EK & QF, if on a J award or above you'll again get lounge access based on flying in the J cabin plus you'll save a bundle in taxes as EK can charge a lot in carrier fees etc.
May be worth investing in an Amex Plat charge card as you'll get access to Priority Pass lounges worldwide, Amex Centurion Lounges, VA Lounges in Australia, AA Admirals Clubs & Delta Sky Clubs.
