No, you don't lose FarmVille. You are able to go between the two but every time you do your other farm will be frozen until you return.
You have to get Surveyors from your friends. In order to unlock the English Freehold (an 18x18 expansion), you need 9 surveyors. This means inviting more friends to play Farmville.
When Farmville loads, the first farm on the right at the bottom (before your neighbors begin) is your Model Farm. It is in the "highest" position. So if your highest neighbor is on Level 100, Model Farm will be to the right of that neighbor at the bottom of the game screen.
Each level you go up you get a farm cash so get lots of exp points :)
If you have enough Farm Cash, you can get a Combine to harvest your crops all in one click. With the English Farm that you get when you reach level ten and complete the requirements to do so, you will get a British-type combine for free.
You can't really get more Farm Cash on Farmville absolutely free, as you often have to pay for it one way or another, even though the offers that they have to get such-and-such farm cash.
