I have two soldering irons, one regular 50 Watts Weller (older model) but similar as WS-51, with a small tip plus a small cute SMD iron, Weller WS-81 with 80 watts of power. This sodering has a very small tip. I use regular 60/40 tin, diam. 0.7 mm. I don't use any solder paste but it's possible. I have also a good pair of tweezers (picture will come), especially made for SMD parts.

Those soldering stations are for professional use and are also (therefore) expensive but you must have two things: Small tip and adjustable temperature. If you can borrow and second soldering iron, it's very practical when you shall solder 0805 parts, like resistors and capacitors.

This is a good model of you want a powerful tweezer but for holding SMD parts the model below is better.

This is a really nice pair of tweezer. Perfect for handling small SMD parts.

 

....more to come.....

 

I have taken photos of two basic configurations. Capacitors are removed so you can see the small parts more clearly.
