I think most people have covered the rake by now, The offset adds a little flex to the fork to enable those fast rides over British bumpy roads, a little more comfortable than straight forks.(from a roadie point of view)
I think you just about have it mate!

Here's just about everything you need to know about rake:
http://www.velonews.com/tech/report/articles/7322.0.html
Most bicycle forks are raked, whether they look like it or not. Older steel forks were raked by curving the blades because joining the tops of the legs to the crown lug in line with the steerer tube was the strongest. It also allowed builders to make forks with different rakes from the same crown lugs, looked good, and added some spring to the front of the bike. Modern straight bladed forks have a sharp bend designed into the crown. Suspension forks have the legs in line with the steerer tube, but offset forward by the crown.

It makes it easier to balance and steer the bike than if the front forks were straight. Even bikes with straight forks usually have an extra piece of metal on the fork to enable the front wheel axle to be mounted slightly further forward then the line of the forks.

if your fork arms where bent u wouldnt be able to get the front wheel on... it sounds like the steerer tube of the fork could be bent and there is no fixing that or u ovalized the bearing cups which depending if the frame is integrated or not u can get new cups for it.. the whole front end could also be too loose or too tight and cause the same problem... and since you have no idea how to fix it since you want to beat it with a hammer, go to a bike shop and explain it to them

It's called rake. Usually between 43mm to 45mm. Helps the front wheel get over bumps better, faster, more efficient. In straight forks, the rake is where the steerer tube and the forks meet.

On the earlier bicycles with straight forks the wheel constantly fouled on the frame, which resulted in the rider being pitched over the handlebars, Sir Walter Raleigh designed the first one with bent forks and thus saved the future of the bicycle.

On the front forks, it improved the castor so that the wheel had a tendency to straighten up. That makes it easier to ride with no hands. The nanny brigade has decided to change things using the following logic:
1) Not holding the handlebars is dangerous
2) Making bikes more dangerous means you have to hold the handlebars.
3) Making bikes more dangerous makes them safer.
Much the same daft thinking as road humps.

It let the designers move the front wheel out just a bit more forward, so the bike had a longer wheelbase (the distance from the points where the wheels made contact with the road). This let them put bigger wheels on the bike, too. These 2 factors made bikes ride better and more comfortably.

it is to set the rake. if you draw a line straight down form the centre of the hub to the ground the contact patch of the front tire will be forward of that line this angle is referred to as the rake. now days it is usually set in the angle of the steering tube on the frame.

What you are referring to is called 'castor angle' & on a bike it makes the machine more stable & easier to keep straight. Racing-style bikes have it for stability at speed, whereas mountain / BMX bikes have none, to aid low speed manoeuverability.
