Some Simple Questions After Just Returning

[MatrixRules]

Hello all, I just returned after nearly two years and have a couple of questions.
1. How do I make an equip able to receive a nebulite?
2. Can the bonus potential lines be reset and if so how?
3. Do the stats on your inner ability go up with your honor level?
4. What's the best nebulite to insert on a weapon (might be subjective)?

Thanks in advance for any guidance you can provide. I'll probably have more questions later.
