Since Pathfinder doesn't share 4e's cosmology or design philosophy, I'd say if you like the 4e versions of Eladrin & Tiefling, you won't like the Pathfinder versions.
Tieflings have a presence in the Golarion setting, most notably in Hell-allied Cheliax, but they're treated very poorly by the citizenry in most cases.
Dragonborn, thankfully, don't exist in Pathfinder.
Eladrin are outsiders. If you're not plane-hopping or don't work them into an adventure as an NPC or opponent, you'll likely never encounter one.
Sorry, I'm not saying you can't convert material from one game to the other, but generally speaking, you're better off picking a horse and running with it. (IMO) You're going to come away dissatisfied if you try to shoehorn a 4e Eladrin into PF while trying to preserve 4e-style mechanics/powers. Your Eladrin is either going to be overpowered compared to the pc-eligible races, lack it's 4e feel, or fall short in some other fashion.
PF & 4e aren't choclate & peanut butter mixing together to make peanut-butter-cup goodness. They're designed to satisfy different gaming styles and tastes. If you're playing 4e, use your Eladrin, Tiefling, and Dragonborn as is. If you're playing PF, use the PF Tiefling, Eladrins aren't pc-races, and Dragonborns don't exist.
