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

Hi, I'm currently using a 4x20 text lcd as a menu display. I have been able to get the menu to scroll vertically, but it scrolls by individual lines. Would a graphics lcd be the way to go to achieve pixel scrolling, or are there some text lcd's that allow this ability?

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

The symptoms of the fault are scrolling wavy horizontal lines about 2-3cm apart, i think its a faulty filter cap causing the problem.

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

Characters type lcd controlers ( like 16x2, 16x4 ), doesn´t have built-in command to perform that function.
In other hand, Graphic type ones, takes control at bit scale.
The only scrolling possible at charater type lcd is changing the offset line pointer of your text.
However the visual effect doesn´t seems like a movement.
