AVR-Chat

Alright, I don't really understand why this isn't working.  I've worked with arduino before, but this is the first time i've gone into bare-bones AVRs(in this case, ATtiny2313).  I'm making a controller mod, where you hit Right-click, left-click, right-trigger to engage rapid fire right-trigger mode, and the same combination only with left-trigger to turn the turbo mode off.  So, this is how I have the pins going for the trip(NOTE: This isn't in the controller yet, i'm just using a DIP-switch and some LEDs for testing purposes).  

PORTD
I:RC	2
I:LC	3
I:RT	4
I:LT	5
PORTB
O:RT	0
O:LED	1

The left shows the function, the right shows the bit in the register.

Alright, time for the code...weeeee.

[code]
#define F_CPU 1000000UL
#include <avr/io.h> 
#include <util/delay.h>

typedef unsigned int u16;
typedef unsigned long u32;


int main(void) 
{ 
	DDRD = 0;
	PORTD = 0;
	DDRB = 0xFF;
	PORTB = 0;
	while(1)
	{
		while(bit_is_clear(PINB,1))
		{
			if(PIND == 0x1C)
			{
				PORTB |=(1<<1);
			}
			if(bit_is_set(PIND,4))
				PORTB |=(1<<0);
			else
				PORTB &=~((1<<0));
		}
		while(bit_is_set(PINB,1))
		{
			if(PIND == 0x2C)
			{
				PORTB &=~((1<<1));
			}
			if(bit_is_clear(PIND,3) && bit_is_set(PIND,4))
			{
				PORTB |=(1<<0);
				_delay_ms(100);
				PORTB &=~((1<<0));
				_delay_ms(100);
			}
			else
				PORTB &=~((1<<0));
		}
	}
	return 1;
}

When I turn the chip on, the LEDs kinda freak out.  The LED output LED stays solid, the RT output LED pulses a bit, but it should be off because i'm not supplying voltage to any of the input pins.  Not sure what to do at this point.  Any suggestions?
