The text length depends on the SMS capbility of your service provider. You can send any lengths of texts and you need to merge all of them at the receiver end to run it all together.
Interfacing a PC LCD screen to a microcontroller is a bit difficult task as it requires a VGA output.
If you choose to use a smaller LCD module, like 16 x2 or even a graphic LCD, PIC micro like the 16F877 or 18F4550 will work fine or ATmega 32, 64 or 128 with atmel.

Ad 1.: Depends on, what kind of GSM module / modem are you going to use and also what technology will transmit your data. SMS are limited up to 160chars / message, but if you'll use GPRS / EDGE / ... it will transfer your data just fine, but it needs little programming on both sides though.
