Improving my chances for the next application cycle?

[Chowder]

I posted here a few months ago about my chances of getting into a funded Clinical Psychology program and received lots of helpful responses. Thanks to your feedback, I'm now feeling much more motivated to start applying again. Here's my slightly updated background:

• Canadian
• Research interests: use of mobile apps in mental healthcare (especially among adolescents), forensic/legal psychology
• BSc. in Psychology (Upper Second Class Honours) - final year thesis on memory awarded First Class Honours
• M.A. in English Studies (Distinction) - thesis on the linguistics of deception awarded 'A'
• Postgraduate Diploma in Education (English)
• 2 years of teaching experience abroad (ESL) - current job
• ~3 years of paid research experience (areas: Education, Psycho-Education, Youth Studies, Linguistics)
• 2 years of student lab research experience (Cognitive Psychology)
• 1 poster presentation at an international peer-reviewed conference on forensic psychology (as solo author)
• 1 symposium presentation in the Education field (as fourth author)
• Volunteer experience as a teacher in youth correctional facilities

My top choices of schools are UBC Okanagan, SFU, and UVic because my research interests are in line with some of the faculty there and I'd like to stay on the West Coast.

Between now and next fall, I'll be working on raising my admittedly awful GRE scores (155V, 144Q, 3.5AWA), but I'm also wondering if there is anything else I could do to improve my chances at admission. I'm based in Asia until at least the start of July; should I start emailing labs or POIs about possible opportunities to work for them in the summer? I'm just a bit worried about my experiences being seemingly all over the place.

Thank you!
