There are several answers possible to your first question.
The different possibilities:
  1) Define a new list environment with a parameter giving the prefix.
  2) Define a new list environment for each prefix using the new-list macro.
  3) Use the enumerate* environment which defines a sublist,
     and manually adjust the corresponding prefix.

In the case of solution 1, you may manually overload the function
kbd-return for the case when we are inside your environment:

        (tm-define (kbd-return)
          (:inside enumerate-prefixed)
          ... code to insert a new item ...)

Please look at what is done for standard lists in std-text-edit.scm.

In the case of solution 2, you may wish to extend the group of
itemize or enumerate environments for each new environment with
a given prefix. This is done using

        (define-group enumerate-tag enumerate-mine),

as you can see in std-text-drd.scm.

In the case of solution 3, the enumerate* environment already behaves
like a standard enumeration. The only inconvenience is that you need
two primitives instead of one for every list (one for modifying
the prefix + one for enumerate*).

Best wishes, Joris
