A bit of advice on products!

[1275GT]

Hi

I'm thinking of spending a bit more time on getting my car looking good.

At the moment I wash it with a mitt and zymol wash, I'm thinking of getting a clay bar kit like the meg's one as it seems a good price.

The car has a quite a few swirl marks but they are quite light so for a polish I was thinking Autoglym SRP but I have also seen this;

Is this any good?

What wax and tyre dressing would you recommend? I would like something that lasts a while if possible!

Thanks
