You can lift our turves with a spade to make the borders wider, but B3's plan of marking out with a hose pipe is a good one, or you can use a bottle of sand.
It rather depends what you want to plant. Plants grown in pots and sold in garden centres can be planted any time. If you want bulbs it is almost daffodil planting time, tulips in November. Then plant perennials in between. Pansies and violas should be in garden centres now or soon. Good for edging.
The orange flower is red hot poker or Kniphofia.
I think your soil could be on the acid side as it looks as though there are azaleas and rhododendrons, but you can buy a soil testing kit in a garden centre. Make sure you use demineralised water for accurate readings.
Dead heading is right. They will need proper pruning in March, you can look it up on Google. But gardening books are good to read in winter.
