1. The list will contain either all selected files or file currently
under cursor (if no selected files). Let's say our list list is held in
variable fl - the snippet code might be alike: 


from os import spawnl
from re import match


for f in fl:
    if match("\.pdf$",f.FileInfo.name):
        # convert f to text using pdf2text
        spawnl(os.P_NOWAIT,dir,’pdf2txt %s’ % f.FileInfo.name)


This is very ugly, but should give general idea how it can be used.
There are tons of python modules for literally everything: starting from
image processing and ending with database access.

2. IMHO it wouldn't be possible. All data will be passed as
procedure/function parameters to plugin. What kind of data data should
be available from gcmd ? Apart from 1) I can imagine only some option
data, but of course it is only my guess...
