If you don't wanna help a player that asked you a simple question then don't, just don't act screw the topic, sty away from it.
I think you need Attack Level on the bow (if it comes with channeling i dunno if its better or not, u alrdy have a lot from the gears), for the gears people say you need minimum 2x channelling on each piece, the 3rd should be dex for the damage, on engraves is the basics, set of ornaments with atk lvl and set of ornaments with def lvls (this requires a lot of work and time, or not, depends on your luck).
