Hello, i tried to weigh each a & b by grams but i somehow ended up with more of part b... the bottle says 100 to 100 what did i do wrong?

It's due to the Resin being heavier than the hardener. Most 1/1 resins have a ratio of about 100/85 so you would weigh 100g of resin for 85g of hardener. Contact manufacturer for exact weight ratio. I use an app that helps me tremendously. "Epoxy Resin Calculator" By Dimitri Urich.

Despite wiping acrylic coasters with a cloth to remove skin oils, the resin pulled back from the edges. No idea how to keep that from happening. ???

Clean molds after each use. Wipe with isopropyl alcohol right before use. Temp changes can cause it too. Heat mat will help

Does anyone know of a pump that will fit these bottles?

No and it's a bad idea. Bubbles.
