I'm also interested in how you classify conjugancy classes on infinite cycles.

Two permutations are conjugate in iff they have the same number of cycles of each type (including 1-cycles).

what about:

(1 2 3)(4 5)(6 7)(8 9)....(2n 2n+1).....

and:

(1 2)(3 4)(5 6)....(2n-1 2n)....

can these be conjugate? why, or why not?
