Protection and economy

[HaoSs]

1)Anyone can recommend me a good economy plugin that works with tekkit ?

2) What is the best protection for a tekkit server ? now i'm using LWC and residence. I like both of them,But residence lacks some options. The remove minecraftOP from admin option is bugged. so basically anyone using a turtle can brake in your house. Any tips ? Is there anyway to make tekkit rune fine without give fake players OP ?

(other plugin i use that can conflict is Authme and essentials protect )
