As a oneWORLD Emerald with your BA Gold, you should be able to call Qantas and request an upper seat if one is available.

There's plenty of advice/opionion in several threads here. Some have distinct leanings/preferences. YMMV

Both, but if forced to choose one, take the Asia-LHR leg.

Quite good, depending upon when you travel you may have a chance of getting Qantas' newer AVOD IFE system, which hopefully has had the kinks ironed out. If not the IFE is similar to BA's system.
