Dome 1 - Ore processing. A small fleet of (mostly) automated mining robots will collect rocks from the landscape and underground, bringing back rocks that can be processed in to ore and used in assembly and repair. Hopefully the rocks will also contain oxides and water, which can be used to supply the crew with Oxygen and Water, and supply Hydrogen for the reactor and visiting space vessels.
Dome 2 - Fusion Reactor, Fission Reactor (for heavier elements found during mining), plus Hydrogen and Water storage.
Dome 3 - Solar farm. Full to the brim with solar panels, which still need protecting from small impacts, etc., so would be kept indoors, or possibly hardened and placed outdoors. Some of the panels collect electricity (complementing the reactor), others are used directly for heating.
Dome 4 - Geothermal plant. Another source of energy and heat for the base.
Dome 5 - Manufacturing centre. Capable of used mined materials to fashion replacement components for the base, new components (such as buildings), using the latest 3D printing techniques to lay down pieces layer by layer and create any object or shape.
Dome 6 - Vegetable garden. Despite being a meateater myself, for efficiency reasons my crew will need to stick to vegetables and vitamin/calcium supplements and whatever else they can grow under the dome.
Dome 7 - Water and Oxygen recycling plant, including aqua purifiers, carbon dioxide scrubbers, etc. No need to waste collected resources when 80% can be reclaimed from what comes out the other end! Even solid waste is going to be reprocessed in to fertiliser for the vegetable garden using algae!
Dome 8 - Habitat. Last but not least, the area where the crew sleeps, lives, conducts science and just has some fun makes up only a small part of the total, self sufficient base. Contains a gym with appropriate measures to keep muscles and bones maintained in a low gravity environment. Also some fun, such as a movie theatre, multisports area, etc. to maintain morale. Also contains an infirmary, with full medical and surgical facilities.
Dome 9 - Maintenance/Workshop - contains spacesuits, ground based vehicles to perform inspection tours, a workshop for fixing components of the base, etc.
Other areas:
Communications dishes - sited redundantly at several points around the base.
Landing pad - for visiting ships.
Emergency shelter - underground, for meteor storms, etc.
