I submitted a question to the census bureau as well and below is what I heard back today. I am still waiting to find out if I still need to link this shapefile to a table though their description doesn't sound like I will have to. I will test it out this week, even if I don't hear back, and post the results here.
"The 2011 TIGER/Line Shapefiles were released yesterday. This set of shapefiles contains a new shapefile, address range - feature shapefile, which has better geocoding results than the all lines shapefile.
The Address Range-Feature (ADDRFEAT.shp) shapefile contains a record for each address range to street name combination. Address ranges associated to more than one street name are also represented by multiple coincident address range feature edge records. This shapefile includes all unsuppressed address ranges and will have better geocoding address match rates compared to the All Lines Shapefile (EDGES.shp) which only includes the most inclusive address range associated with each side of a street edge.
The TIGER/Line Files contain potential address ranges, not individual addresses. Potential ranges include the full range of possible structure numbers even though the actual structures may not exist. "
