First of all when you are a Civvy-U student the only thing that the military is truly concerned about (obviously there is more but the jist of it is):
1. You enroll in full time studies and submit the tuition claim
2. you submit claim for Textbooks, PP&S (up to the annual limit)
3. You do the EXPRESS Test by 31 Dec of that year
4. You pass all your courses, you don't drop a course without permission, you don't change academic programs without permission etc
5. You don't get into any legal or financial problems.
6. All medical services are to be used in accordance to the medical policies
7. Need leave passes to leave the geographical area
As a civvy-u student you are responsible for(obviously there is more but the jist of it is):
1. Your housing, your food, your costs, you pay it, arrange for it, buy it etc
2. Submitting claims to your ULO, booking your EXPRESS test, submitting leave passes
3. Going to class, pass your courses, and be available for Military training in the summer periods.
The SEM does not care whether you live at home, in residence or in a rented apartment, your friends basement etc. They don't care how you eat, these costs are your choice, and you pay them, they are not deducted from your pay check.
Regarding having a part-time job, it is up to the discretion of the SEM and ULO. Many students do it, just make sure you clear it first and make sure it does not impede on your scholastic abilities.

http://www.forces.gc.ca/dgcb/cbi/includes/cbi_coverpage_e.asp?sidesection=6&docid=4 download this PDF, go to page 20, those are the rates for 2008 for all of Canada. These are adjusted each year. Just to point out a few things, the PLD rate is based on where you live not where you go to school. So generally if you are going to go to a school downtown Toronto, live downtown, its worth it!!! (unless you can live for free elsewhere, otherwise the rent is not much different, but the PLD doubles!). To find out what the geographical areas are covered by each of these cities your ULO should be able to provide you with the map zones for each area. Also PLD is a taxable benefit, but a nice one still.
Also PLD is the same no matter what your rank within the REG Force.
