I agree with the above poster. Sharp chains are the key. The 455 is a fine choice for what you want/need to do. Having actually used one, I'd recommend it for your purposes. Just keep whatever bar it comes with, it'll do fine. Regarding all the other stuff, despite how it may come across to you, not a single person on this forum was born knowing how to use a chainsaw, sharpen a chain and split firewood. You have a source of wood. Get a saw, get some knowledge on how to safely use it and get to work. As far as getting the firewood from the woods to your house, pick up a piece in each hand and carry it there. That works, not complicated. This will lead you to develop ever increasing methods of wood handling. A wheelbarrow works perfectly fine for moving wood. A little trailer on the back of a riding mower is an improvement. A trailer behind a small tractor is better yet. And so forth. You'll make mistakes and learn as you go like everyone else that has done similar. Your back up saw for now can be a bow saw and an axe. Later you may want a smaller or larger chainsaw (or 50 or them....) but start somewhere and enjoy your new place.
