I am not sure what type orchid that is....the initials before the name will tell you what family it is in. There are several informational posts if you search on repotting, that have been done in a step by step manner....and whether you have a catt, or oncid or den...there should be some pretty good information on what to pot it in as well.
On the opening page where your screen name is at, there is the "enter the orchid talk orchid forum" button. Click on the Senior Members question section and the common topics section. There you will find care information for the various types of orchids as well as potting information and many other subjects that are often common problems or questions that nearly everyone has. Repotting is very well illustrated and I think you won't have any problems after seeing the old posts.
I hope this helps you out....Bruce will probably add a link for you soon if you cannot find what you need. Also, anything you cannot find, feel free to do a post on. Alot of times, how you pot things depends on how you water and where you live. It is very humid here so I use a very dry potting system on almost everything whereas someone in Chicago might use spag on the same plants due to the lack of humidity there.
Good Luck..
