i have pre-order but do i need cd's??

this has been on my mind for a while i have pre-order and cause i have it i can play faction BUT when i get my real faction i mean cd's and key do i hafto install using the cd's? cause when i was playing pre-order faction i coulden enter some portals,this has realy been buging me i need answears..

u can use the cd's 2 get the content you havnt got

NOTE

some portals will not open unless you have completed the right primary quest and using the cds will not change a thing

so if i get this right you mean if i just enter my Faction Key ill hafto download the rest of cantha but if i use cd's i dont hafto download anything?

so what should i do then use the cd' ore just download it ore dosent it matter?

you dont have to use the cd you can download them if you want it's up to you and no it dosnt matter

oh yeah forgot why dont i have primary quest whith my lvl20 tyrian char? i have done like 8-10quests but non of them are primary,and what are those imperial commendations?
