I activated the pause last year, so can answer the questions. It seems too good to be true but it does work as VA says and is a great benefit
1) They are 'earned' but the whole point is that for the period you are on leave the SC's do not count towards retaining status.
2) Yes. Parental pause ended 26 January, platinum m'ship restarted, and I am now Plat again until 26 January 2014.
3) Yes. Same as (1) - you will earn points and SC's from family members pooling to you. You'll accrue the points but the SC's do not count towards tier retention
4) The SC's you have already accrued are really "moot", as when the pause ends you receive a full further 12 months. So in my case
- Requal date was September 20
- Pause began August 26
- Platinum recommenced from 26 January and I have 12 months to re qualify plat.
So I have now been platinum since September 2011, and will remain so until January 2014.
5) No, has to be 6 months and you cant have a shorter pause
6) Yes, was pleasantly surprised that that all benefits such as lounge access, preferential seating allocation, luggage allowance continued during the pause. I also received a bonus complimentary upgrade sent to all WP's while the pause was on.
I did lose the 1 complimentary upgrade that I hadn't used by my original requal date, but this was more than compensated for as when my account reset on 26 January another 4 complimentary upgrades were added. The hotel group and rental car options however still show as "opted in" so they weren't reset
