Step 3: Assembly and Resources
The needed tools:
Solder (lead-free is preferable)
The hardest part would be soldering the FTDI chip on to the board. If you are new to SMD soldering, I would recommended to do some research or study the tutorials of how to solder the SMD components before get your hand on it.
Here is the list of sites that offer such a tutorials,

These are the four parts videos that I used as the references of learning how to do SMD soldering,

Following the first and hardest part, should be easy enough to solder all the other components in. Works on the components that close to the center first and moving outward.
