Hi Bob,
I hope you will enjoy QGIS even more, when you find out how to do
things properly ;)
You do not need external sotware to import a csv file.
Menu Layer -> Add Layer -> Pick last item from flyout "Add Delimited
Text Layer"
Browse to your csv file and properly assign the x and y field columns
and resume.
Your point layer will get added to the canvas.
If you didn't change any options under Settings/Options/CRS
beforehand, your project is in default WGS84 EPSG 4326 and your new
layer will have WGS84 as well by default (change settings to e.g.
being asked for the CRS when a new layer is created if you like.)
The coordinates of your csv file are in WGS84 too, so this part is ok
in this case.
You previously loaded layer is in another CRS.
Check under Menu Project/Project properties, that "Enable 'on the fly'
CRS transformation is ticked. Then your two layers will be aligned
correctly.
As you only imported the CSV so far, it is still a CSV which you can't
edit. To make it an editable shape file, right click the layer in the
layers panel and choose "Save As ..."
Pick the path where you want to store your shape file.
If you want to change the new layers CRS so it's the same as your
other layer, you will first have to find out the CRS.
To find out, in which projection this layer is stored, double click on
it in the layer panel to get to the layer properties and check the CRS
under "General". In your case, this is NAD83 with EPSG-Code 4269.
When saving the CSV as ESRI-Shape, search and choose this CRS, and you
will receive your reprojected points as a new layer.
Hope this helps
Bernd

To summarize, when I use QGIS to add a layer with some points on it
to a layer with a map, they don't show up in the right place. I'm new
at GIS work (but enjoying QGIS!)
I got shapefile tl_2014_us_state.zip from
https://www.census.gov/cgi-bin/geo/shapefiles2014/main and loaded it
into QGIS. Next, I used https://code.google.com/p/csv2shp/ to convert
the following CSV file to an ESRI shapefile:
"lat","long","name"
40.712700,-74.005898,New York City
34.049999,-118.250000,Los Angeles
it creates all the necessary files except for the PRJ file. I tried
copying the PRJ file from shapefile tl_2014_us_state for the
generated data and loaded that layer, and I see dots for the two
cities, but far, far away from the US, and one of the dots looks
north of the other instead of east of it.
Here is that PRJ file. I'm guessing that I should be using a
different Coordinate Reference System, but I have no idea which and
how to specify it:
GEOGCS["GCS_North_American_1983",DATUM["D_North_American_1983",SPHEROID["GRS_1980",6378137,298.257222101]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]]
Any suggestions?
Thanks,
Bob
