Australia, New Zealand & the South Pacific - Advice required/ seating

G/day all,
Need some advice regarding seating on our trip to London by Emirates.
We are booked on the following aircraft and would like to know what you would consider good seats in economy class.

Perth to Dubai = Airbus A340-300
Dubai to London= 77w ( 777-300 i think)
Rome to Dubai = 773 ditto i think
Dubai to Perth = Airbus A340-300

i am not too clued up on these aircraft and not a frequent flyer so any help or tips would be great,i'm 60+.

Thanks and best wishes to all

Emirates has a forum on Flyertalk where you'll likely get more response.

(Or, the moderator will probably move it...)

Refer to www.seatguru.com - it's quite useful. The 777 aircraft have the most generous seat pitch for economy at 34 inches.
