I dont know how many toms you are using so I'll assume 3
SM58 on the snare, you may get some bleed from the hihat
E835 between the Hi and Mid tom (to taste, play around with the tom placement)
For a generalized, overhead use the 990 but if your picking up too much snare (likely), use the 991 because its more directional point it away from the source thats overpowering. If you have the 990 over the drummers head, you may get a nice mix of the cymbals, then you can use the 991 for a hi hat mic if you want.

As far as left and right, thats a taste thing (I use Cubase). Assuming I had a kit with hihat, 2 crashes, a ride, 3 toms, snare and kick.
Kick and snare centered.
Crash 1 - 30 left
Crash 2 - 30 right
Ride - 45 to 60 right
Hihat (if I miked seperate) - 24 to 60 left
tom 1 - 45 left
Tom 2 - center
Tom 3 - 45 right

Thats my starting point but I tweak a lot while working on drums, I also do it from the point of the drummer

The stereo imaging will only be happening at the mix unless you are only recording to two tracks with your kit. Then follow the previous instructions. If you are recording each mic as a separate track then it will be mono no matter what until the mix.
