I can't speak as to the quality of the staff or agents where you live, but I can tell you that if you're not satisfied with whoever you get assigned, you can ask for someone else. Another friend is going through the process and is on his 2nd realtor. The first just wasn't a good personality fit.
Some of the basic landlord stuff you can learn online and the legal stuff will be covered in the required landlord training class.
Just a thought about numbers .... A triple will pay for itself (management, repairs, etc) but a quad will throw off income - even when you build in a repair/replacement reserve. If you have the lifestyle to swing a 4-unit (usually 1-2 bedroom apartments, at least here in Buffalo), I would absolutely recommend it. My plan is to reinvest the most of the income back into the property until I'm satisfied with its condition and then start putting away for a downpayment for another income property - since that one will require 10-20% down.
