Hmmm.  Are you using the CCS LCD driver file, lcd.c?  It looks like you
might be, since that file includes lcd_send_nibble().  If so, it's also
got an lcd_putc() function you can use to save yourself some tmie and
effort.  I'm not sure what the rs parameter of the function above is
doing, but lcd_send_byte() needs two parameters.  I think sending printf()
output to a function will only work with a function that takes a single
parameter -- printf()  will call it once for each character in the
resulting output.  Doing this:

printf(lcd_putc,"value in memory is %02x",NUMBER);

should get you there, assuming you have a function lcd_putc() that takes a
character as a single parameter and spits it out to the LCD.
Alternatively, if the port_c=rs bit is impoprtant you could maybe do
something like this:

***WARNING*** untested code ahead!

char x = 0;
char buffer[25];
sprintf(buffer,"value in memory is %02x",NUMBER);
        // puts output string in buffer
while(buffer[x] lcd_send_byte(rs, buffer[x++]);
        // calls lcd_send_byte for each character in buffer
