PE Seats

Hi Everyone,
First post for me, so I hope you can help! We're flying back from LAX to LHR (VS8) on 30th July and just about to book our seats. I will be traveling with my wife and 6 year old boy. First time in PE for us so I just wondered if the armrests between seats lift up the like in economy, so son can lay across us and his seat to sleep or do I just get him a window seat and let him curl up in that!!
Also I have 34G,H,K on the way out (VS7) out I noticed the G seat is staggered forward by almost a row (we had this problem In economy last year)31A,C & 32C are still available do you think this is a better option!! Aircraft is showing as 747 both ways
Thanks Dave
