If you want a mountain bike for trials, I would suggest any bike under 25lbs with non-curved tube frame, under 14 inch frame size.
No such thing. Trials is a sub-sport of mountain biking, often called "mountain bike trials". It's a sport similar to motorcycle trials where one takes a light bike and hops around an obstacle course. You might have heard "BMX" and "trials" in the same sentence because a BMX bicycle can essentially make a good trials bike with minimal modifications.
Yes, the Greater Swiss Mountain Dogs are very good at agility trials.
There are too many good mountain bikes to mention.
Urah it's good
Mountain bike shoes are not required to be able to ride a mountain bike. You can wear any good athletic shoe. Wearing an actual mountain bike shoe is helpful however to keep your feet from slipping from the peddles on rugged terrian but it not required in any way.

http://www.houstonbiketrails.com is a good website to find mountain bike trails and bike paths in the South Houston and surrounding areas.
There are a few good mountain bikes tires that would suit a 18 speed bike. I would go to a bike store and ask.there's different tires for what type of riding you doing but everyone have their own way they like their bikes from handle bars to tires. There's no best part. It's just what's good for you
If you want a do-all hardtail then you'll have to spend at least $700 for an all mountain hardtail. for under $300 though you can get a pretty good BMX or dirt jump bike. but like a said, for a mountain bike, you'll have to save up a bit more.
I would suggest a bike with a small frame and a long seat post if you want a low seat for jumping, but a larger frame if you ride mountain and street more.
rockey mountain flow 1.0 is the way to go
