Question on gear ratio

As some or many of you know I'm looking to buy a truck. I found a 95 ram 1500 Off Road Edition. It has a 5.9 5 speed trans and the 4.10 rearend. So my questions are...

1. What rpms would I be turning with the 4.10 gears and say 32" tires at 60 mph?

2. What is the optimal rpm to run in these trucks at cruising speed?

3. What would be my top speed with above mentioned gears n tires?

4. What size tire would be the best suited for the combo?
