are there mods that just change the inventory? i liked the way btmod handled it, but i'm using immersive interface, so i won't get the changes if i use btmod. any suggestions?

DarN's UI. Note that it's incompatible with Immersive Interface but the latter isn't needed as you can mimic its settings with DarN's.

DarN's is the best one around IMO. And you can have a darker version of it if you're so inclined.

Yeah, DarN is great. But I like wz_Inventory too.

It is in DarN's too! You have the option to use the default list or wz's boxes.

Indeed, all that needs to be done is shown in post 2 of this thread.

I like the separate one you can download because you can highly customize it using Tweak Oblivion.

Ok. so i found larger inventory. all i want to know now, is if the map is a different entry than the inventory? the reason i want to know, is because i like the elven map mod, but i need to know if its compatible

Yes. The map is a separate file.

As already said: The map itself is a completely separate thing. DarNified (etc.) does change how much of the map is displayed, but not the map itself.
I would recommend TheNiceOne's http://www.tesnexus.com/downloads/file.php?id=35969 if you are using any number of mods. (And no, that is not just because my own older set of Elven Maps is being used as the base )
