I would not recommend seats in the back, they are bumpier and smellier back there. Depending on the length of your trip go for a bulk head seat. You'll be able to get a bassinet for it and it will make your lives much easier. You'll need to call in to request it and when you check in verify that you have it. Trust me on this, I have travelled many times starting at 2.5 months to 4 years and bulk head offers more room and is much more comfy then getting squished in the back.
Breastfeeding is the best way to go, if your doing it. That way you don't have to worry about heating up bottles. Alot of airports offer family changing areas where you can breastfeed if you are not comfortable doing it in the lounge. And in the planes most people are uncomfortable watching you and will normally turn away. Taking off and landing may be alittle hard for the ears, but just latch him on and he'll do fine. I find that most of the time the lull of the engines during boarding and taxiing will put them to sleep, so I rarely have had any trouble during take off. A nuk or a bottle will also help.
This is actually the easiest time to travel with a child. All they do is eat and sleep, so their schedules will not really be affected by jetlag. Just make sure you bring plenty of nappies and a change or two of clothes for him and he'll do great. It will probably be harder for you then for him, so don't worry and relax.
Enjoy your trip.
BTW: Check your stroller in at the airplane. That way you can move around the airport easily.
