WysiWyg is a rule used in alot of tournaments, which effectively require you to put a model representing a specific wargear effect on the field. so if you have a melta gun in your squad you need a model representing a melta gun. so no 3 shouldnt be a problem since weapons can not be targeted anyway, it has to be a main part of the body you can see, so head chest legs or arms.
as for 2. I believe that theres something about you can not put a model on a smaller base, but you could put it on a bigger base, with the exception of some models (Canis) it should not be a problem, even with the stiff anal retards out there
as for 1. its a difficult grey area, since I have seen people complain about it all the time, like for making a sniper in a prone position would come into this question aswell, which the asshats will bitch about, making something taller wouldnt do much though.
