your mod plan is how i started out too.
on bumpers you need to decide between full width, mid width, stubby or very minimalist. looking through the lifted and respective 2dr and 4dr threads above you should get a great selection of what people have put on their rigs and find what suits you.
personally i went with stubby so that i could more easily get a tire onto a rock to crawl up it without a pesky bumper in the way.
if you are definitely planning a lift that includes new coils in the future, then i wouldn't worry about the extra weight of the bumper. it will almost definitely be heavier then the stock one, and lower your front end some. i drove and wheeled for a couple months after my bumper before i did my lift and wheels, and couldn't really tell. i did do front and rear bumpers at the same time so i didn't have any real rake (forward lean), that might be a difference if you are keeping the stock rear bumper.
in your steps, the only things i think are missing:
buy beer and get a friend over to help. mounting a bumper alone can be a pretty annoying feat. especially if you go with a nice solid metal one.
and, also you need to be prepared to do some wiring to get the winch powered, and if you have factory fogs you may need to rewire and mount them if the new bumper has places for factory ones. or decide to go without or buy new ones to mount on the bumper.
again, welcome. the fun is only just begun. modding the jeep is second only to taking out on the trails in my opinion. and planning, researching and prepping for the next phase of mods falls right in third place.
