Digikey (www.digikey.com) has the solder paste.
Though in my opinion it isn't really needed for a small repair of one or
two components. I use a regular Weller ~60W temperature regulated
iron. I think I've got a 700F tip installed. After removing the old
component and residual solder, apply a _small_ amount of solder to one
pad. Hold the part on the pad with tweezers and heat it until the
solder flows. Remove the iron and wait for the solder to freeze.
Remove the tweezers and proceed to solder the remaining pins. Try to
heat the components as little as possible while still getting a good
connection.
As a side note, if you are working with some types of power components,
the large heatsink tab may require a 100w gun to get the job done.
Oh, ramsey electronics has some SMT kits that you could use to try your
hand at SMT before attacking any expensive automotive electronics.
