The Cessna TR182 got the same warning system basically. Unfortunately, there is no certified method to connect it to the audio panel. The better the ANR headsets get, the less audible the gear warning becomes.
Ideally I would like to install something like
this but I haven't found any EASA approved products.
Regarding no flap landings, over here when you want to land at a very busy airport where they always have 3-4 planes on the ILS, you only get your chance when promising 120-130KTAS on short final which means no flaps, quite some power and gear up until shortly before threshold. Often they also tell you to touchdown in a specific area so you can leave the runway quickly. When IFR, they also like to give you special instructions for a missed approach (basically omitting the mile long straight leg). No time for checklists in any of this.
