October and November is the best time for laying turf. It can be laid December -Feb providing the soil isn't frozen or waterlogged . March and April would be the next best for laying turf but it more prone to drought the main killer, and it will take longer to establish due to the ground be colder.
Like pansyface said use some scaffold planks for levelling, I prefer to use the back of the rake for firming the ground as long as you can firm it down hard enough but using your feet fine as well. Any bump and hallows you missed can be address when laying the turf. I buy some top dressing just in case for filling in gaps, or it can be used to level out any small hallows in spring after the grass has started to grow.
Best to do any work on a dry day as well, it will make the job a lot easier.
