I think that GATE 7.2 cannot yet directly read DICOM files with CT data. 
The current version on GitHub does have support for reading DICOM images 
(though I did not yet try that out myself). It should be available in 
the upcoming release.

About Question 2) and 3): Did you read this section of the user guide:

http://wiki.opengatecollaboration.org/index.php/Users_Guide_V7.2:Voxelized_Source_and_Phantom

You may also want to have a look at "example2" in 
examples/example_Radiotherapy. In "examples/example_dosimetry/" the 
"external-beam-therapy-photon" and "protontherapy" may be useful for 
inspiration.

About Question 1): There are several ways to convert DICOM data to 
"mhd". I have used "vv" for that:

http://vv.creatis.insa-lyon.fr/

The VV tool is useful both for visualization and for image format 
conversions. It is advertised in a few places in the User Guide, maybe 
we should advertise it in more places, in particular in the voxelized 
source section of the user guide.

If you are fluent in Python then you may want to have a look at 
"SimpleITK" (http://www.simpleitk.org/): that allows you to read and 
write (and manipulate and analyze and ...) DICOM and MHD images.

Hope that helps,
David Boersma
