If you want to flash the rom without a pc, just google "how to flash rom without a computer" and look at the first link...the guide might help.
Otherwise, after you have rooted just install a custom recovery (like twrp or cwm) and flash the rom from your sd card. And make sure you wipe cache/data etc before flashing the new rom. (make a backup first)
