Inexperienced Weave gurl

I'm so obssessed with my weave.... I'm sure this topic has been talked about over and over. But I'd like some specific advice.
I recently got a weave with Black Diamond Italian curly hair. It's been about a month and I just figured out how to tame it. I comb it with a wide tooth comb twice a day, and sprtiz it with water and conditioner. I've washed it twice already, it's just goregous after being washed, if I blow dry it with a oil sheen. If I leave it to air dry it's a disaster.

But like I said I think I found away to control it, any other suggestions would be helpful though.

I want to try to Rio Wave by Black Diamond next. It's a very loose body wave and I want to know if I'll need to set it, or if I can just wash, comb and go. Can someone please let me know what the best styles are for:
- Wash and just blow dry.
- No ironing, no setting

I want to try so many different styles, but because I'm so inexperienced with weaves, I'm afraid I won't know how to care/style it when the time comes.

I prefer full head sewn in, no hair out, because my natural hair is so over-relaxed it doesn't know whether it wants to go back curly or straight. I don't want to deal with my natural hair when wearing a weave.

Help Please!!!
