    Does anything come up when you try to power the phone on? If not, you are probably hard-bricked and best bet would be to either turn it in for warranty or find someone to use the JTAG device to reload the OS for you(once stock firmware has been released). The JTAG service usually runs around $40 to $70 plus shipping.

    The Stock rom has not been released for that device, so you will have to wait for Samsung/USC to release the stock rom for somebody to make an odin image of it.

    Looks like your stuck with it in that condition until the stock firmware is released. Do not try to warranty it.

    You flashed new firmware to it without the stock firmware available and without doing a backup? Risky.

    This is exactly why I won't root it until the re-image file is available.

    What you need to do is download flashing software and a Sprint ROM for the SGS II Epic 4G. It's the same phone, except it has WIMAX.
    Here's where you start. http://forum.xda-developers.com/forumdisplay.php?f=1281
    Do your homework before you go flashing anything. Consider this a valuable learned lesson.

    Also you ABSOLUTELY CANNOT flash a ROM from a GSM phone onto a CDMA phone even if they have the same name. If you don't know the difference between GSM and CDMA, do your homework.

    Yes, as long as it is for the same device plus you will just need to load the US Cellular PRL. You wouldn't have to, but to keep the phone from roaming too much so they don't terminate your line for the 50 percent rule.
