[Qgis-user] Question about changing Project for Vector Layers

Sorry for the lengthy email.

Got a question about changing the projection for the following to WGS84:

I received shapefiles info for my neighborhood but the projection is in
NAD_1983_StatePlane_Mississippi_West_FIPS_2302_Feet (NAD83 / Mississippi
West (ftUS in QGIS)

In my project settings I have WSG84 set as the default projection as well as
layer units set to Decimal Degrees.

For some reason unknown to me, it does not appear that the projection is
displaying in WGS84.

>From the Properties MetaData Tab, the following displays:

In layer spatial reference system units : xMin,yMin 2349376.08,1066253.54 :
xMax,yMax 2353354.03,1070858.08
Layer Spatial Reference System: +proj=longlat +ellps=WGS84
+towgs84=0,0,0,0,0,0,0 +no_defs

>From the Coordinate windows at the bottom of QGIS canvas, the lat/lon
displays as the following:

2351256, 1069360

When normally it displays in WGS84 as

-90.155924, 32.439683

How do I go about changing to a WGS84 projection display and save those
changes to the attributes.

The following is a MetaData Extraction from the my Shapefiles.

Thanks in advance for your help on this request or could someone point me to
some a QGIS example that would help.
