Tutorial Recommendations?

[Khaalis]

Hi all. I am looking for recommendations on what the best tutorials are to go through to do the following process:

1) Create continental landmasses in Gimp/Photoshop (I have both)
{EDIT} I will also want to import the base image into GPlates to help with mountain and island location
2) Create a decent starting bump/heightmap for those landmasses
{EDIT} Then I'll will also want to use GProjector

I then want to take that and import the finished shapes and heightmap into Wilbur to convert into MDR to import to FT3. From there I'll use the Israh tutorial to refine the details. (Or any other tutorial that may be more applicable?)

Part of my issue is that there are SO many tutorials floating around that I have no idea what is best for attempting this process.

Thanks in advance.
