The real fiddly work has already been taken care of for you with the mounting of the SMD components. If you had to install some of those multi-lead packages on a PCB then I would truly despair.?
What you have to install are discrete components that are leaded; resistors, capacitors and transistors and to hand-wind the inductors and transformers. Your greatest chance of error there is a solder-bridge, breaking a component package by bending the lead too tight, installing something backwards, not getting the insulating varnish off of the enameled wire or confusing what lead is what on the six-leaded twisted transformer.
Use a good iron, magnifying light or optical loupe and a DMM to test for shorts or verify component values if you suspect anything. The instructions are very explicit and you need to read and understand every word as you follow it precisely. Maybe it would be easier to print out the assembly instructions and use a pen or highlighter to mark through each sentence as you do it so you don't skip steps or install the wrong component.
I started assembling kits when my father, who was a ham back in the 1970's needed someone with a steady hand and good eyes to assemble his Heathkit radios. My brothers had no interest in it but I did; and I am darned good with a soldering iron. The QRP-Labs radios are the easiest I have ever built with the most well thought out instructions.
