Do I need to remove the bumper to install this?

No. This bolts directly to factory mounting points behind the bumper cover. Bumper removal isn't necessary, but some builders prefer to remove it for easier access and cleaner bolt torquing.

Will this interfere with my bumper sensors or parking assist?

This reinforcement bar sits behind the bumper skin and does not contact sensor housings or wiring. No modification to sensor placement needed.

Can I paint this before installing it?

You can, but most builders install it first and paint or wrap the entire front clip as one unit. If you prime and paint beforehand, allow full cure time before bolting down to avoid finish damage during assembly.
