In regards to my RRSP- Can I still claim my RRSP amount if on my paystub it shows up as "Pretax" thats deducted? I contribute to my RRSP through my employer.

Yes, but you can only enter what is actually shown on your RRSP Contribution slip you receive. If your employer contributes to an RRSP on your behalf, you will receive an RRSP Contribution slip and need to report it in the RRSP section.
