Item Trades
Honestly, I don't find myself overly picky. Anything from my item wishlist (see previous blog entry: /blogs.php?entry=19&id=5511886) at a similar value is probably good.

Pet Trades
Unfortunately, this is where things get narrowed quite a bit. I don't find myself rather picky about names other than tacky misspellings of real words, "ship" names (think "Sonamy" or "Destiel", not "Titanic" or "Lusitania".), or xXx_NAMES_LIEK_DIS_xXx. Really, what this boils down to is the pets' species and costumes (with a minor influence coming from stats and collections). I almost always prefer redone/recent costume art to old costume art.

TL;DR version: I like reptiles (including birds and dinosaurs), futuristic aesthetics, and cute things; names don't really matter; avoid edgy things or furries and we can probably strike a deal really quickly.
