Can anyone suggest Training for Licensed Client?

We are integrating our Sales Cloud with Eloqua.  We dont have budget or time for an implementor and have exceeded our knowledge base over our implementor.  We need to make our admins self-sufficient in Eloqua, particularly in the Sales CLoud Sync for over 22 business units.  the task is dubious made even more complicated with lack of standard sync functions such as the following from implementation document:

"When Sales Cloud lead records are deleted or merged, these changes are not synchronized to Oracle Marketing Cloud. "  Seriously? 

Seiously?  So we as admins have to go through a process to open up Eloqua and delete and merge Sales Cloud records?  We hope this is no longer accurate?
