No lead.

SN100 by Balver, way better than the usual lead free SAC type of solder.

Get a decent regulated soldering station (e.G. Weller or Ersa).

Avoid small tips.  Soldering is so much easier if the tip is short and 
broad. Its all about heat flow. A small tip has a hard time to heat a pad 
connected to a ground plane. Use the largest tip that fits between the 
pins. 3.5mm is good for 0805 SMD parts. 

Don't try to solder SMD IC pins one by one. These videos demonstrate how 
to use surface tension to your advantage:

It really works!
Note the size of the tip.

Get a bunch of steel wool to clean the tip when oxidized.
