Claying is easy mate, just make sure you use loads of lube with it. You will start with too much, but thats fine, you soon get the feel for it. Also make sure you start with small chunks so that if (WHEN!) you drop it, you dont mind throwing it away. Also check out DetailingWorlds guides they are the best
With the tyre shine, get yourself a foam applicator. I just recenty got one and it makes it so easy. Just spray on the applicator and wipe it around the tyre. No getting it on the drive or alloys and nice even finish
