Would recommend Milan Flight Gear for when you decide to get the pedals. Personally I used flight sims without rudder pedals for quite a while before I finally got them and would say that having the pedals makes a big difference. Rudder assist will help you make coordinated turns which is fine but sometimes you need to apply rudder and ailerons in a way that isn't a coordinated turn (such as during crosswind landings etc). It's definitely worth getting.
