Encouraging Baha'is to...

Huququllah is the equivalent of tithing. It is less demanding than a lot of religions as it is a requirement to donate 19% of ones excess wealth to the UHJ (excess wealth is defined in a somewhat complicated way from memory, there's manuals on how to calculate it iirc but essentially it's meant to not touch any finances required for day to day living), so Baha'is aren't supposed to donate anything they can't afford.

Baha'is are also encouraged to donate to the fund, which is entirely voluntary and there isn't any 'required' level of donation. Off the top of my head I don't recall official authoritative guidance being too demanding, but there is a lot of Baha'i 'folklore' which is sometimes cited by lower level officials and rank and file Baha'is which encourages people to be irresponsible financially to support the fund. Depends heavily on the community though and I wouldn't say it's been a huge issue in any community I've been apart of.

Mentoring isn't really well defined, it's language which has sort of popped up as part of the institute process. The Faith has no 'clergy'. In practice all the administrative functions of clergy are present in the Faith, but not the spiritual ones, so in my experience mentoring is, in theory, a way of fulfilling the spiritual functions of clergymen in other religions (i.e., studying scripture, teaching the theology, etc.), but instead of being an official appointed position it's an informal procedure. In practice it's more about getting rank and file Baha'is to encourage people to participate in the institute process, which is the formalized way the Faith evangelizes. The Faith's institutions are meant to be pretty hands off unless someone breaks a rule, so its official institutions can't really order people to evangelize, so in my mind the House is out-sourcing the task of getting people to support its teaching plan to peer pressure.
