Hi Steve,

Don already provided some good links for tutorials.
Just let me add that I have a hollow tip for my Weller (Cooper tools) 
soldering iron that acts like a small solder bath which you can move 
over the pins of TQFP ICs after applying some flux. It rella works 
like a charm and after some practising you get none to 1 or two 
shorts (mostly at the first and last pairs of pins) which you have to 
remove with desoldering wick. 

When SMD became mainstream I first (like most?) thought that this is 
the end of hand prototyping, but after trying and developing some 
technique and tricks I now like SMD more than thru-hole. I like 
espacially that you don't have to turn the board over and over like 
with wired parts (plug part, turn, solder, turn...).

OK, BGAs are a little bit harder ;-) (and I'm lucky to have a small 
SMD soldering tunnel available (on weekends) at the company where I'm 
working) but many people modified some electric BBC furnaces into SMD 
soldering stations with good results by adding an electronic control 
for the temperature profile. You should be able to find more info 
by "Googleing" a bit if you're interested.

HTH,
Stefan
