Sounds about Large (8' to 16'). Huge is 16' to 32'.
If you want them to be immune to fire, just give them Immunity to Fire and Cold Vulnerability.

The immune to to fire and heat comes from fact they from a desert environment. From what you said I keep getting that they should have the fire subtype. The only problem with that is they do not have any fire-based abilities.

Are there any monsters I could look that might help me out in making them?

The more I think about it the more I think they should have the Outsider type due to the fact they are from another dimension.

Would there any way to give them hawk-like vision?

You know, extra dimensional generally means outsider.

That is what I thought about Outsiders.

What if they have 9D8 Racial Hit Dice and Fast healing 4? How much should they weigh?

Is there anything I could look online that would help me out with making them?

Should they have a bonus to hide while in desert setting?

+8 to inverse the size penalty to hide

low light vision gives vision twice as good in most conditions
