Is there a keyboard shortcut or ability to show the radius of other buildings (market, gathers, etc) while you are placing a new building? I haven't seen anything in the keyboard options and would like to see them for building layout and placement.

Citizens need a source of food and warmth to survive. Since the Help Menu states that citzens will only visit the nearest storage barn to collect resource then you can't depend on citizens going to your primary settlement to get resources. Even if they do take the long walk back to your primary settlement they will be wasting a lot of time doing so.
Your best bet would be set-up a Market near the offshoot settlement to ensure all the goods the citizens need are close by. Market Vendors will gather resources from Storage Barns and Stockpiles all over the map, so it'll ensure that citizens will always have the resources they require near by. The long travel time between the Market and your primary settlement could still cause some problems though, so you may need to put several vendors in the Market to ensure the Market always has a sufficent number of supplies.
Another option would be to build a gatheres hut, forester and woodcutter. The gathers hut combined with the foreseter replanting trees should ensure they have enough food. The woodcutter and logs provided by the forester should ensure they have enough fuel to keep warm. I suspet they won't have access to clothes with this method, but that will just decrease their productivity. So long as their homes are warm they won't die they should just work less and spend more time indoors where it's warm.
I'm confident that's a fair trade as not only are you increasing your overall food stores, you're also increasing variety which is good for overall health.
Citizens in Banished require a variety of different types of food in order to maintain high health, this includes meats, vegetables, and fruits. The more variety, the more healthy your population will stay.

If you pin the buildings of interest, their radiuses will continue to display while you place your next building.
