In this case, TTL won't give you the right exposure sometimes, especially the reflecting surface is over or under-reflective. In theory, you could do calculation, but do you really want to measure bouncing distances while keeping your subject in focus? I'd take a couple of shots, look at histogram, and dial in manual compensation on the flash. That's it.
In my experience with Nikon system (d90 plus sb600) the exposure is mostly right. I routinely bounce flash to the upper left so it gives the subject somewhat more 3d feel. In typical indoor home situation most time it is adequate. That said, canon flash system (t3i and 430exii) gives less consistent result . One crucial point you need to pay attention to is use CTO (orange) gel to match the color of indoor lighting. Otherwise the color can be really weird. Sometimes I like use orange gel for the subject with background of natural light. This can give nice effect where the subject is warm with cool backlight of blue hue. This really can enhance the skin tone with a nice contrast. In large indoor situation bouncing lght won't work well because the reflecting wall or ceiling are too far away. -r
