Yes, I am an OMS candidate.
Regarding procedure of admission, there isn't much difference from other category candidates except that we are supposed to submit our MAT, etc. scorecards after the GDPI, most probably in the beginning of the month of June.
For OMS, there are 9 seats in each of the courses of PGDBM and MMS.
The last student that made it into Syd last year had 168 total score. And 99.87 in MAT meant 135 marks. Given that 33/40 in GDPI is not very difficult, I guess this is the kind of percentile you need to get to make it into Syd. Yet, I think the cut-off might still go higher because of the increasing competition.
The infra is good and is improving at a fast rate.
Regarding placements, etc, you can visit the website of the college:

And yes, it's cutoff remains second highest after JB if you're asking how the college fares
