make sure you get a spring compressor, apart from that there isn't much to worry about apart from the top nuts! You have to hold the strut still with an allen key while you try to loosen the nut, it can be a total nightmare!
I had to get a windy gun on one of mine in the end, I'd advise you to pop it into your local garage and hand them £5 to crack the bolts loose for you, then nip em up and take it home to finish the swap.
