No, only the parameters matter.

Should be no problem with OTF enabled.

If I load a file with that projection, it gets identified as
EPSG:2992 NAD83 / Oregon Lambert (ft)

That is the extent of whole Oregon in that projection.

This gets identified as EPSG:4269 NAD83

An area south of Portland.

I have started with a project in EPSG:3857, added Openstreetmap 
background from the openlayers plugin, and the extent points as 
delimited text with the EPSG codes above.

Make sure that QGIS prompts you for CRS of new layers, and delete .qpj 
files that may come from earlier tries you did.
