Hi assa99, my experience of similar situation in Feb this year is for;
1. that you sign on for JSB as soon as your employment ends, the company should have listed this date in the initial notice of redundancy (consultation) document package. The date will be confirmed in the termination documents he gets at end of consultation period -2 weeks in my case.
2. not sure - I think so & included these in my calculation- but waiting to get this confirmed.
I'm just about to post a related question on maximising pension payments in year of redundancy which you should have a look at & hopefully answers given.
