Best shop in Houston is Motorcycles Unlimited on 1960. Tell him Harrison sent you.
You can not possibly beat his service, and it WILL always be done right. I could go on and on about them. I drive 45 minutes to get to them when I need something instead of going to the many places closer.
There are TONS of rides and roads in the Houston area, but most are somewhat kept to the riders that know them.
The BEST road is 3090, but it is currently under construction and tons of gravel. 390 is good, 949, 149, 224... 1774 (i think)....
There are alot more but I don't know the actual names.
Where in Houston are you? I can show ya around if you are northside.
