I have flown with goggles that have 60 degree FOV and to be honest found no noticeable difference when compared to the standard 40 degrees, so I wouldn't make that a major purchase decision.
The most important thing is to make sure that the goggles and cockpit lighting are compatible. We found out the hard way that when they are not life can get very 'interesting'.
As far as helmets go that is pretty much personal preference. I use an Alpha Eagle, which I find very comfortable.
