Bicycle Mechanics - Question about tires?

Im lookin at a purchasing a mountain bike and the tires need to be switched from serious knobbys to somthing a little less aggressive and more road/dirt track worthy, i was looking at these....

but the only size available is 026/175 and the listed tire size for the bike (since i havent purchased yet) is Innova 26"x1.95", i need some opinions here about whether these will work or what i should swap to that will work.

Those will work just fine.

Depending on how much road vs. dirt you're riding, you may find that some 1.5" slicks are even faster for your road riding. (You may need new inner tubes though, depending on what you've got.)

Here's a similar tire to what you posted-

These are what I use, which my LBS sells for $20-

I have the Drifters on a bike and I do like them. A co-worker like the Serfas Barista. Less tread and a little skinnier. I haven't used them, so I can't give an opinion about them.

But, my co-worker likes them.

I've got these (Kevlar version) and find them quite smooth and quiet on pavement, with some paddle-style grip on hardpack. They're on sale now, too: http://www.performancebike.com/shop/profile.cfm?SKU=14789&subcategory

Yes, those would be good. If you're not riding on loose stuff, slick tires are best. Tires with a slight tread won't hurt, but they won't help, either.
