i always do experiment for different problems.. Presently i am doing analysis of finned tube.
1. How to model gas passage, solid(tube ) and water passage(inside) tube. i used the concept of frozen option for gas passage and neglected tube surface second domain i select for water that is soli (add material-extrude) but... in case if i want all the 3 domains seperate what steps i follow...!!
2. for meshing i choose regions like GSAINLET,GASOUTLET,WATERIN,WATEROUT,INSIDE TUBE-SYM-1 SYM2,OUTERWALLGAS AND OUTERWALL GAS, FOR FINNED SURFACE I CHOOSE TWO WALLS OPTION... AM I GOING RIGHT ..

I don't understand what you are asking.
Your first question is weird. This sounds like a straightforward CHT simulation and you just model the air, liquid and solid as different domains. Forget about frozen options. A some tutorials on CHT simulations. (CHT = Conjugate heat transfer,ie heat transfer with both solid and fluid domains included)
I don't know what you mean by your second question. Are you referring to the interface between solid and fluid domains? That is just a domain interface, either 1to1 or GGI.
