"Awaiting EO Processing" for 2 weeks after submission. Should I contact?
Depending on the journal, two weeks isn't really a long time for editor assignment. Your manuscript might be at the end of a pretty long queue that might take time. Moreover, getting the right editor for your topic is also sometimes an issue. 

Another point to note is that ScholarOne is not always up-to-date with the process of the publisher. This may also depend on the frequency of updates sent from the publisher's editorial office to ScholarOne. 

In my experience with ScholarOne, I had "Editor now searching and inviting referees" for about a month before I received the review result, "Resubmit [with minor edit]". There was no "under review" status in between. Hence, there was nothing to worry about.

If this is prolonged over a month, you may send a polite request for the current status of your manuscript through ScholarOne helpdesk. They are very helpful in this regard and usually reply within a day or two.
