I wouldn't use 58's on toms. They are designed for vocals and are completely wrong for making toms sound good. What I means is...depending on the sound you are going for, they may tend to work against you. They are hyped in the upper mid-range which is not the best part of the tom-tom's sound character. They also, by design, don't pick up much below 100 Hz, which is a big part of the tom-tom's sound character.
I use mics that are far more flat and extend deeper into the low frequencies.
But if it's all you have, I guess they are OK to learn on. On the other hand, many people have gotten good recordings using 57's on snare.
Keep experimenting.
