As Jorden wrote, a fast lens and a camera light are always a good choice. In addition, I'd suggest the "ISO 160 rule":
With all Canon DSLRs I know, ISOs with multiples of 160 (160, 320, 480, 640...) are much cleaner and have noticebly less noise than the others. So try using them. Should be possible natively with the 60D. If not, Magic Lantern will help. With my T2i ISO 640 is even cleaner than 400...
