best trail bike accessories?

[Steel]

I want to make my YZ250 more tuned for trail riding.
i am thinking of the following:
brush guards
skid plate
headlight
flywheel weight (if i go with a e-line headlight, it comes with a 12oz weight)
fork tuning?
frame guard (what is the main purpose of a frame guard? to prevent boot rub on the frame?)
hour meter
anything else?

I am just looking for a range of recommendations from those of you who modified your 2-strokes for trail riding, to find who makes the best product for each in the list. :cool:
I ride technical trails in northern NJ.

Steering damper for sure. Possibly a supsension revalve.
