iTunes problems

Just AIFF ripped 900 CDs mostly classical with dbpoweramp. Using iTunes for playback and file management. iTunes is certainly not made for Classical CD structures. The rips come off the CDs in order and iTunes immediately randomizes the track numbers. OK for pop songs but it doesn't work for a symphony with 4 movements. I can use Album Sort most of the time to place them in order but that destroys the search pattern I use. Is there any way that the track order can be forced to stay in its proper order?

I'm also thinking about moving to J River or other system but I'm not a computer guru so all the full featured aspects of these front ends probably mean I'd not have fun running them. Can any of them sort to two levels say Composer and track name so I can get all Bach contatas or whatever. I'm running a Windows 7 Pro server NAS nad Ayre USB DAC.
