Like everyone above here ^ LED downlights would be optimal for creating more task focused and general lighting in the space. Due to the nature of your pendant shadowing occurs when the light is on during the evening, this can make it hard to use certain bench space as task areas. If you are unable to do downlights (which can be the case for many customers) wall lights on your task areas would be the next best thing! Try using single spot lights above the areas you use as service spaces, spots that are adjustable would be great as it will allow you to adjust the lighting, be sure that whatever style you select that you pick something that doesn't glare at eye level as this will make it uncomfortable to work with.

depends on what colours and styles you like..check out "raked pine ceilings with fan in HOUZZ photos for lots of ideas eg

Have a look at Glosswood. We have used it extensively at our house, and had been up for years and still looks brand new. Can get it from Bunnings but best to deal with the local distributor. Manufactured in WA I recall. I love the look of plywood, but not everyones taste or style.

What height window and doors are you proposing. If 3 metre ceilings then 2400 doors and windows would look better. This will then add extra cost for window treatments. Also in the kitchen, with a 3 metre ceiling, where would you stop your overhead cabinets, would you have them to the ceiling? Or standard height? I personally would do your pitched ceiling in living area, and 2700mm everywhere else. This will add extra interest with the change of ceiling height. 2700mm are a good height.
