I think you can do better on those pedals, for example: Long Term Review: The Unbelievably Light & Affordable Xpedo Spry Platform Pedal - Bikerumor

If a slightly higher profile is OK, you cannot go wrong with the durability of shimano pedals: Shimano MX80 Saint Pedals > Components > Pedals > Platform Pedals | Jenson USA

As for the saddle, give it a few months so that you can either get used to it or be able to pinpoint exactly what is wrong with it

If you lock the bike up a lot, you may consider replacing the QRs to slow down the thief and maybe even some sort of frame protection to prevent dings and scratches. I sometimes use a soft rubber tape to wrap the frame tubes
