1.
I love Werewolves but i love Orange eyes more, so after all of the Dawnguard missions are completed including the main and side quests, basically to the point where there is nothing usefull there anymore do i have another chance to become a VL, such as talking to Serena and after becoming a VL can i have my awsome doggies/trolls? She offered it before the soul carn but i noticed most of the DG hate you after that so i reloaded to tear my soul. Onto that part, can you re enter the soul carn as a human?

Short: So can you have 100% of DG finnished then become a VL?
Short: Can you re enter the soul carn as human?

2.
The next thing i was wondering is how does Vamparism play out? Do you just get the VL when you are infected or is it the same as vanilla but with orange eyes? Because i could realy care less about the VL and would be fine with it that way, as well as doing my simple method of being a Werewolf Vampire mainly to get the badass eyes yet retain my wolf skill (because i dont think it works with VL + WW)

Short: Is contracting Vamparism the same?

3.
Next thing is how far before i get the reskinned light elven armor (Ancient Falmer Armor)? ""Can i possibly run to it and get it right away? if so where is it?"" Does it have any variant male or female with the shoulder pads? I mean if you look at the armor in your invetory it has shoulders, but i guess when you equip it the pads go away, so what would be the point of bethesda making an armor that displays reskinned shoulderpads but they are not in use.

The last point on this is if no shoulder pads are displayed then do you get sleeves on male or female like the original light elven armor? Or are you simply wearing a armored version of a wife beater?

Short: Can i get Ancient Falmer Armor early? If so where?

4.
Can you get Harkens Robes? And does it look the same on a female as the Royal/Serenas robe does? I tend to not like the cleavage on the vamp armor and royal robes for female since for some god awfull reason it looks like [censored], some probably have no issue with it but for some stupid reason it just does not look right.

Short: Can you get Harkens Robes?

5.
Do you get both castles? I mean it would seem like if during dawnguard you become a VL you would get the vampire castle instead of DG Keep.

Short: Can you get both castles?

Lastly:

Crossbows for every material? In or out, i keep hearing you can have ebony, deadric etc....
That is about it, at least what i can come up with.

anyone?

yes, harkon robes are in the castle near the soul cairn on a shelf. They are called royal vampire robes
