Ooh, that's too bad.
That LCD needs 11 control lines.
Had to hunt around for a datasheet on the display

Green common anode part, so you need to fool around with PNP transistors or a UDN2981 type part for multiplexing too.
0.3" viewable at 3 meters (10 feet).
So, 11 for LCD, 7 for segments, 4 for digit selection, 2 for serial, and you still have those 25 other LEDs, need 3 or 4 more digit selection lines, so so yeah, you're gonna need some additional hardware, or a processor with more IO pins, like something 1284 based, with 32 IO.
