Some structural planting to soften that fence would be good Simon. It would be worth getting some trellis on it and putting a few climbers there. I'd be inclined to create a border along the front edge and have some planting along there as well to give a little screening and make the deck seem more secluded. Grasses would be good as there are loads of different heights and shapes to choose from, and the flowers spikes give a bit of movement. You could mix airier types like Miscanthus and Stipa with the aforementioned Phormiums. They won't like sitting in heavy soil so you'll need to spend a bit of time creating a good environment for all your plants first, as you said.
If you have other planted areas round the garden you could use some of the same plants to give a bit of unity. Repeat planting is very effective to link areas of the garden together.
