Transistors

Hi,

I am new to electronics and working with transistors for the first
time. I chose 2N4401transistor from Fairchild to begin with. You can
find the data *** at http://www.fairchildsemi.com/ds/2N/2N4401.pdf

I have following questions

1. The base current Ib controls the collector current Ic. But I am
unable to find the base current from the data ***.

2. I am also unable to find the maximum and minimum values of Ib too.

3. Is it ok to determine Ic and then calculate Ib using Ic = beta x
Ic.

4. What should I consider to do regarding DC biasing of the transistor
before applying the AC signal to the transistor?

Please advice!
John
