Not sure what you mean in the first problem, it might be that the _lcd_SHIFT_LEFT and _lcd_SHIFT_RIGHT move the lcd display position, not the text.
In the second problem, you have for(;;) which is an infinite loop, it will never finish, unless you break out of it using the break; statement, or limit it with a counter like the other

In a 16x2 lcd no, but you can try this fucnction it is quite efficient:
void ScrollMessage(unsigned char row,const char Message)
unsigned int MHead=0,Done=0,counter;
if(row >1) row=1;

yes Graphics lcd is the way to go if you want to go a vertical scroll. Character lcd's only let you control individual rows of characters. In graphic lcd's you can control a row of pixels.

I attached the datasheet of an lcd which I feel is slightly more understandable than the rest. Anyway, the basic idea is that the output of an lcd mirrors the data stored in a RAM. So, you can carry out all sorts of fanciful effects, as long as the RAM is updated accordingly.
And yes, the cursor is a special feature that can be enabled/disabled us

You don't need different ports to interface 2 lcds. You can have DB0-DB7, RS, RW pins common. Only EN pins of each lcd will go to different pins on the microcontroller.
What do you means by floating from right to left? You mean scrolling ?

First, you have to realize how the memory in an lcd is mapped. The two rows in memory aren't separate. Assuming you are using an HD44780-based display, the first row starts at like 0x00 and the second row starts at like 0x40. If you want to scroll just the second row, you need to write your own routine that will only shift the characters over from

The negative oltage generator on board the lcd is used to supply a negative bias for the contrast. The one side of the contrast pot is connected to Vdd the other side to Vee (the negative voltage generator) and the wiper of the pot is connected to Vo.
