.iff files

[bsmith32]

I've downloaded several landscape items that are .iff files. What should I do with them ?

I believe those are files for the first Sims game, in which case they would not be compatible with the Sims 2.

Delete them. ;)
Yes, as IgnorantBliss said, they are for the original Sims game and will not work with the Sims 2.
