Did I destroy my trucks clutch?

I have a 1996 ford ranger 2wd 5 speed. I was pulling out of a slightly muddy field onto a road, so I started my truck in second to prevent my tires from slipping. I was surrounded my dogs and was trying not to hit them. I thought I had my foot all the way off the clutch but apparently I didn't.
The truck started to rev really high as I rolled onto the road, so I thought I was just in neutral. So I put the truck in first and it did the same thing, accompanied by a burning smell. I quickly realized it was the clutch and pulled over. I turned the truck off for about 10 minutes.
I put the clutch in and she started fine. Put it in first and she drove away like nothing had happened. Went through all the gears like before with no grinding, and the RPMs were the same as before the incident. Only thing different was that the clutch peddle felt "different". Like it didn't extend all the way up. At red lights I would put the truck in neutral and pump the clutch and it felt fine. Other then that the truck drove just like before.

So my question(s) is/are:
1) Is my clutched f***ed, or did I just mess it up a little
2) Is my truck okay to drive (only vehicle so it has to be driven at least to work).

Its probably ok, they can take some abuse, but not often. If it is adjustable, you might be able to get the pedal where it was. If it shifted fine, then it won't hurt to drive it.

You pretty well took what was left out of it. You can still drive it but it's on limited time before it goes completely out.

The fact that the clutch isn't slipping implies that it is a matter of adjustment. Your truck has a hydraulic clutch and that usually self adjusts for wear, but there are exceptions and severe overheating is one of them. You can find the instructions to 'bleed' your clutch online (on a number of sites) and if that returns the pedal to normal then all is well, if not then you may need to replace the pressure plate and throwout bearing (never forget the throwout bearing).

To test your clutch (carefully) you can place the transmission in second gear, hold the brake (at idle speed) and release the clutch fairly quickly - the engine should immediately staff with almost no slippage of the clutch - the more slippage the worse the condition.
