How much do you use Heaven's Gift? If a lot, keep the armour.
How often do you need to sleep? I prefer restoration potions, but the portable bed is weightless. If you save before loading up, you can always re-load if you trigger than overload bug.
There is not a great need for telekinesis in the wastelands. If you have at least one level of Repair, you can fix stuff on-the-fly, and there is a merchant there who can (I think) repair as well.
Do you need a boost to your resistances? If so, keep the elixirs. Sell the purple potions; they give a very small health bonus. I sold my super health/mana/restoration potions, since I had more than enough minor and standard ones.
