Why higher value of roll off is disirable for a filter?
The higher the rate or roll-off, the higher the out of band attenuation.

What is relation between roll off factor bandwidth and bit rate?
The roll-off factor of a digital filter defines how much more bandwidth the filter occupies than that of an ideal "brick-wall" filter, whose bandwidth is the theoretical minimum Nyquist bandwidth. The Nyquist bandwidth is simply the symbol rate expressed in Hz: Nyquist Bandwidth (Hz) = Symbol Rate (Sym/s) However, a real-world filter will require more bandwidth, and the excess over the Nyquist bandwidth is expressed by the roll-off factor. Suppose a filter has a Nyquist bandwidth of 100 MHz but actually occupies 120 MHz; in this case its roll-off factor is 0.2, i.e. the excess bandwidth is 0.2 times the Nyquist bandwidth and the total filter pass-bandwidth is 1.2 times the Nyquist bandwidth.
What is the Difference between ideal and practical low pass filter?
Ideal filters having sharp cut-off & sharp cut-in for LPF & HPF but in practical filters there is some roll-off rate based on the order.

In audio electronics what is the most common use for a high-pass filter?
http://en.wikipedia.org/wiki/High-pass_filter. It removes the lowest frequencies from the rest of the sound. AKA bass roll-off or low cut.
