For cable guides,you have several options. You can buy ready-made like these:
Stick-On Guides | Jagwire
Universal Cycles -- Problem Solvers Stick On Cable Guides
Problem Solvers
...or just fab your own with zip ties,P clips,and such. P clips or zip ties with bolt holes will also sort the fender mount.
BTW,the stem setup looks interesting,could we see a better pic of that?
