I haven't converted tiger files in forever, but I can tell you a good strategy for getting 2000 Census Data for the State of Louisiana. Go to the ArcGIS Living Atlas of the world and search for 2000 Census Data. A number of layers will come up. I got Population Change, for example; it has State, County, Tract, and Block Group geometry. Once you have your geometry, you can join it to the census data you need (the layer I got has several 2000 fields). You can also use the Enrich tool to get other 2000 census data fields including these:
The Enrich tool does use credits, but they are very affordable (especially compared to the time it takes to find, clean, and join the data from other sources). Also, a trial version of the software comes with some free credits. I hope this helps!
Best wishes!
