Finally, a topic I do know something about. I spent alot of time in a cabinet, millwork shop and do alot of cabinet and countertop work in my own shop. I use a Crain laminate scoring tool to cut my laminate down to workable size first. It is basically a carbide tooth mounted at an angle in a plastic handle. I clamp a straight edge over my laminate onto my table saw outfeed table, score about 3-4 passes, at least through the colored layer, unclamp and then fold the laminate into the score. The opposite of scored glass. I use the table saw for cutting to width after I've cut down managable pieces this way. You could cut every thing with this tool if you wanted to. Practice on some scrap first if possible till you get the feel of it. You can also a router with an 1/8" straight cutting bit using a straight edge, just offset for the setback on the router edge to bit distance. Whatever you decide, try to make your cuts a short as possible, i.e. cut to length first out of the 4x10, then cut your width, if that makes sense.
