I have heard that I can use a vrt file to merge multiple geotiffs into one?
what is the syntax?
gdal_tranlsate -of VRT file1.tif file2.tif file2.tif
Something like this?

No, you need to use gdalbuildvrt The instructions on the page are pretty clear, but to save you a mouse click, one of the examples is:
gdalbuildvrt doq_index.vrt doq/*.tif

Ah...I see i have gdal 1.6.0. I guess this is only from 1.7.0 Commented Mar 14, 2012 at 17:22

It was compiled by default from 1.6.1 onwards. It's worth biting the bullet and upgrading to 1.9 for the extras as well as a good few bug fixes. An alternative would be to look at the page describing VRTs and construct one by hand. It is then treated as a regular format by the rest of the tools. Commented Mar 15, 2012 at 11:11
More specifically to merge multiple tifs in one directory.
gdalbuildvrt out.vrt *.tif
gdal_translate -of GTiff -a_srs epsg:900913 in.vrt out.tif
gdalbuildvrt will build a virtual vrt file with all your individual .tif files, but if you want to convert the .vrt back into a big single .tif file, you need to use gdal_translate.
