Complications in my application..................

Hi, guys I am planning to study in Canada for may 2012, and applied for couple of universities International business management course in University of Concordia, and same course from University of Saskatchewan with IELTS 6.5 overall. It was a way long back since I have applied and cannot wait till whole fall intake for admissions and attended an spot admission for Centennial college and got admission in Project management so I am thinking of waiting till Feb ending and and if any admission letter from any univ is granted then I will go with the univ or else I will apply with college.

The main complications are as follows,

1. I have finished my Graduation in 2007 with 63% and 19 backlogs.
2. Gone to UK in 2007 sep and finished Post Graduation in Management Studies in 2008.
3. In the 4 years time in UK I never visited India I mean I never came back to India not even for 1 week, so now if I apply to Canada the
   V.O. might think this applicant might not leave the country in future and the chances of rejections are positive?.
4. My PSW visa in Uk got expired in Nov 2010, and immediately applied for another student visa extension, they kept me wait for 10 months
   in sep 2011, I have cancelled the application and asked to send me back my application and want to leave the country and they have cancelled my application and sent back my application. But in my passport it doesn't say anything that I have applied for further
   extension and cancelled later the only proof I got is an letter saying that this applicant has applied and withdrawn the application,
   will it create a problem for me because while entering into India in 2011 sep Mumbai Immigration people stopped me inquired me for 3
   hours asking me what I was doing for past 10 months like that.
5. I heard people saying that do not submit documents unless asked so shall I submit that letter with my application or wait till they
request. I am in big confusion and dilemma weather to go for it or just drop out

Experts please help me with proper suggestions either I have to apply or to quit the plan....
