Hi Daemon, firstly a very warm welcome to the scale models forum where I hope that you will find some very usefull resources and gallery postings and I hope that one day you will share some of your own experiences with us all.
The first thing I would suggest is that you put 'washes' or 'drybrush' into the search facility and see what has been discussed already on the subjects but one of the best links we have all seen recently was this one:

A superb site with just the sort of step by step tutorials that you are looking for. I hope that you enjoy it as much as we all did.
