QFP soldering

Hello, all:

        I am finally getting around to building the P112 Z180-based SBC from
Dave Brooks (I got one of his last unpopulated boards). It has two 100-pin
QFP chips (the Z180 and an SMC Super I/O chip), so, I bought the blade-like
SMD soldering iron tip for my iron.

        So, here's the stupid question...how do I solder these things? Do I
hold the iron parallel or perpendicular to the package leads? The board is
pre-tinned, but I should I also tin the QFP leads?

        Any help appreciated.
