hi james welcome to the detailing section and hope you have deep pockets

right firstly ditch the sponge and chamios

have you read the stickys at the top of the section? these will help you get a rough idea of how to do things and at what stage to do them etc theres also some good pics to look at too.
routine:
WASHING.
spray wheels with non acidic wheel cleaner and allow to soak while your getting everything else set up
aggitate wheels with a wheel brush or seperate wash mitt,never use the same washmitt you wash the body with for cleaning the wheels, re-apply cleaner if needed
wash car using 2 bucket method and a lambswool mitt of microfibre mitt(read stickys for full info)
clay using clay bar and plenty of lube(this is to be done only 2/3 times a year, full info in stickys)
rinse the car over again to remove clay lube
dry the car using a large drying towel.
POLISHING:
by hand or machine to remove imperfections like scratches swirls spiderwebbing oxydation orange peel, using various grades of polishing compounds and different pad combo's when doing it by machine,(more info and pics in the stickys)
SEALING:
sealants are applied after the polishing stage to protect the paint/clearcote from ultra violet damage and contamination etc. durabilty depends on the product and how its applied, can vary from 6 months to 12 months etc
WAXING:
final stage using a high grade carnauba paste wax which gives your car a deep gloss and a very hydrophobic coating which will repel water and protect the paint but this will diminish over time and will eventually need re-applying this will also be product dependant as they all vary in the amount of carnauba used in the recipes by different companys.
and finally dont forget to clean and polish the glass which alot of people leave out or dont pay much attention to

have a look at these sites and read through the various products which are set out in the relevant sections for each stage of the process.
