Question on Getting Started:

I will answer the second part first. Most clubs can be bent about 2 degrees safely. Any more could possibly cause a break. Some cast clubs can still be bent to 3 or 4 degrees without a problem though. Forged clubs can generally be bent further than cast.

The lie angle is the tilt of the toe down away or up towards the shaft. Down would be considered negative or flatter. Up towards the shaft would be considered positive or more upright. There is a perfect lie angle for everyone and for a lot of players it is not "standard" lie. It is important to get a proper fitting and to make sure your clubs are bent to match your personal needs. If an iron is too flat, your ball will tend to go right and if it's too upright, you will hook to the left.
