Soldering
Yes, do it now. Use the BOM for identifying the components.
Results:
Stick a about 2.4mm high sticky pad on the bottom like this:
Did you bridge J1 on the TFT pcb to enable 3.3V operation? Do that before soldering the adapter board onto the TFT.
Next, solder the adapter board onto the back of the TFT display:

Questions
How big is the Display Adapter PCB?
It measures 38.1 × 38.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Display Adapter use?
2 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Display Adapter KiCad files?
From the atoomnetmarc/IoT12 repository on GitHub, at the commit this page was made from: the board is hardware/Display Adapter/Display Adapter.kicad_pcb and its schematic hardware/Control Board/IoT12 Control Board Brain.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Display Adapter design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
