As far as I know all of the character kits from Wyrmmaster use magnets. Studio does not recognise poser magnets at this time and may never use them. As for Poser all the stuff you mention should work fine unless you don't have the full victoria 3 from Daz (http://www.daz3d.com) The version of Victoria that comes with Studio is the RR (Reduced Resolution) version and only textures/clothes will work with that model. For victoria 3 characters and morphs to work you will need the full version and the two morph packs that go with it - around 60 dollars investment. If you already have the victoria 3 model (not the RR version) then you just need the head and body morph packs as almost all the characters available use those rather than original morphs.
