Employment contract/law advice

I have recently left an employer and require advice/2nd opinion on a few things...

1. I want to check that I understand my obligations/contract restrictions correctly as there may be a future conflict of interest.

2. The parting from my employer wasn't on good terms and he believes he has ground to 'terminate my employment contract' as opposed to serving notice and settling notice period/unused holidays etc.

I can email a copy of my employment to you along with the questions I have early Monday morning (before 9.30am) and I am looking for a detailed response same day.

I don't believe that there will be more than 15-20 minutes work in reviewing the relevent sections of my contract & responding to my questions.
