I define my own versions of \part and \chapter (called \Part and \Chapter) and specify a different display style using setups. The definition for \Part is below, \Chapter is very similar so I haven't included it.

%% Double rule above part title
\startsetups PartSetup
 \setupheader[state=empty]
 \par
 \startMPcode
   draw (0,2mm)--(TextWidth,2mm) withpen pensquare scaled 1.5mm ;
   draw (0,0)--(TextWidth,0) withpen pensquare scaled 1.0mm ;
   clip currentpicture to unitsquare yscaled 1cm xscaled TextWidth
 \stopMPcode
\stopsetups

\define[2]\placePartTitle{\midaligned{#2}}
%% The above line is what I use. You want Roman numerals so maybe adapt it to:
%% \define[2]\placePartTitle{\midaligned{\convertnumber[Romannumerals][#1] #2}}

\definehead [Part] [part]
\setuphead[Part]
 [ page=right,
   placehead=yes,
   style={\stylePartTitle}, %% this is just from a \definefont
   before={\setups{PartSetup}},
   command=\placePartTitle,
 ]

With \setuplayout[location=doublesided] this then comes out on the RHS.

For the ToC, I use:

\setuplist [alternative=b]
\setuplist [Part]
 [ headnumber=no,
   margin=0cm,
   width=0cm,
   distance=0cm,
   style=\tocStylePartTitle,
 ]
\setuplist [Chapter]
 [ headnumber=no,
   margin=1em,
   width=0cm,
   distance=0cm,
 ]
\setupcombinedlist [content] [list={Part,Chapter}]

then \placecontent prints the chapter titles indented under each part.
