I would suggest checking Photographer's Ephemeris for the dates that you're going to be there to determine position/time of sunrise in relation to your subject. We got some really nice shots there at sunset, but our guide knew when and where to set up.
I just checked and, if I recall correctly, the main temple will be back lit if approached from the usual entrance across the water.
Photographer's Ephemeris available as both an Ios and Android app.
