Your Honda dealer or online site would be your easiest source for the bearings and ECT sensor.

Be sure and get replacement seals for the headstock bearings while you're at it.
Keep the old races to use when driving in the replacement new bearing races, unless you have the special tools on hand.

You may need to toy with the bearing preload torque after replacement so the forks swing freely side to side.
The factory torque spec is the starting point.

The Tyga carbon-fiber front fender is actually cheaper than new OEM (and looks awesome).

Bulges? Not good at all.
Did you happen to check the manufacture date on the tire?
Usually its molded on the sidewall in a 4-digit pattern of 2-digit year and 2-digit week.
So 1302 is 2nd week of 2013.
A tire is at most, good for 5 to 6 years, even when sitting on the shelf.
Shorter if the tire is exposed to a hot environment, more if the tire is in a cooler environment.
What happens is the plasticizer degrades over time and the tire loses flexibility in the carcass and tread.
