How to update the land use land cover data in WRF model ?

Hello Sir/Madam,
I downloaded the MODIS 500m, MCD12Q1 land cover data for my parent domain from Google Earth Engine in .tif file for 2010 and converted it into binary file using "gdal_translate -of ENVI foo.tif data.bil". It created a single binary file then i renamed it into the format given in WRF manual "mv data.bil 00001-ncols.00001-nrows".The projection of the downloaded .tif file was "WGS-84". MODIS data has 17 land use categories which is same as IGBP MODIS NOAH except the Tundra and lake classes.
I have three questions.
(1) Can anyone suggest me to which projection i have to reproject it ?
(2) How to prepare the index file?
(3) What changes i have to make in the GEOGRID.TBL and VEGPARAM.TBL next to proceed further.

The namelist.wps file is attached below. I am new to WRF platform so please help.


Thanks in advance.
