After doing some research (something I should have done in the first place), I was able to find information on this subject, which I hope to have understood correctly. In the interest of helping those with similar questions, I will post my findings below.
1. DEO Payscale appears to begin as 2nd Lt, according to this post: http://army.ca/forums/threads/116852/post-1336866.html#msg1336866
As mentioned in the above thread, pay can vary based on Deductions, PLD, and Provincial Taxes. Also, Rations and Quarters will vary depending on if the DEO member is Married/Common-law or not.

Around 1500 as a 2lt (twice a month) in 2011/12. There are many variables involved however that getting an answer to your question may not be close to what you receive, such as:
Entry plan as a DEO (previous service? are you going in as a substantive 2LT or LT? etc)
Are you married (or common law) and maintaining a residence elsewhere besides St.Jean? (this will get factored into PLD)
And a few other misc considerations (Land Duty Allowance, etc).
2. I have yet to get official confirmation, but it appears that an Allowance is supplied to return to your Next of Kin for the Holiday Break. That being said, be sure to list the proper person as your Next of Kin.
3. Based on my findings in 1., it appears that this is incorrect as DEO BMOQ members recieve 2nd Lt. pay from Day 1. This needs confirmation however.
Hopefully this is all factual and helpful. With the age of some posts and recent changes in policy, the information available was sometimes difficult to discern.
