Regarding the Brake hoses:
I'd urge caution when thinking about adding support. They must remain flexible throughout the limits of the suspension's travel. Adding support could be a set-up for catastrophic failure.
Regarding the Tires:
Appearance is only part of the story. To get a more precise feel of their suitability for continued use, I suggest you find an inexpensive Durometer having the Shore A scale (your tire dealer may have one). Check the reading of a new tire and compare it against the readings you get from your tires. Especially the sidewalls. Rubber/Synthetic Elastomer is funny stuff and often loses resiliency over time. A tire may look great but have been damaged by prolonged exposure to UV and weather. You may see some difference in the readings you get from the inside and outside sidewalls of a tire. The tread is also important because as rubber ages over time alone, a tire's ability to sustain traction in the wet may be compromised.
A simple example of this is an old pencil eraser, which, as you've probably noticed, has become harder. It doesn't work as well as a new eraser, does it?
