Bit too new for me this one martin, my manual doesnt cover yours, but the speakers will be easy enough, just go along to your local audio stockist, you will then be able to listen to all they have, as audio is a very personal thing, what sounds good to me may be horrid to you.
My local place has been able to sell me and fit an electric aerial cheaper than I could buy it from halfords
On another occasion they sold and fitted for me, a sony cd player, all done for £30 less than I could buy it from the argos catalogue
If you want a manual for your car, to cover all the things like washer jets etc, I found the haynes to be useless, but the bentley is superb.
