Mike,> Is it safe to assume that the placement all the way into the corner is the preferable one? <
Yes.
> Note the sloping ceiling right and left. How do I calculate first reflection points on such a surface? <
Side wall first reflection points are at ear height, about halfway between your ears and the loudspeakers. (Actually, a little forward of the halfway point.) So a curve in that direction isn't a factor. This article on my company's site tells how to calculate the first reflection points:

However, you can also use the "mirror trick" to be certain, as explained in this article:

> Will Modecalc give me any useful information <
Not really. ModeCalc is most useful for someone who's designing a new room, and has the luxury of determining the room's dimensions. For a room that's already built all it will tell you is which frequencies will resonate. But even that is not so useful because the correct solution is broadband absorption that works well to as low a frequency as possible.
