Financial Planning for Financial Independence and Charitable Giving

Hello!
 

I've looked into old posts on financial planning for charitable giving and, as I found most have some years and they're not completely adapted to my situation, I decided to ask away.

A comment on this post convinced me that I should not wait for complete financial independence before doing, at least, a 10% pledge (which I understood is the community standard yet I'm not sure if for somewhat arbitrary reasons or any specific reason). The reasons for not waiting were the urgency of the causes, the compatibility of achieving financial independence and EA goals and the possibility of value drifting due to non active involvement.

Yet I do need to pay debts before giving so I'm making this my first goal. I've been feeling I don't have the financial education necessary to effectively plan and execute a plan to achieve this first goal and the next ones. What kind of advice would you give me and what (free) resources would you recommend?
