From what I know is you can test after 6 weeks or if a sore appears which it would. I don't know information about the specific tests.

Syphilis tests aren't done by IgG and IgM.

You want either an RPR or a VDRL.  If its positive, make sure they do a confirmatory test.

Yes, that's more than sufficient for conclusive syphilis results.
