sam,

please use the regular (external) tachyon renderer this will
create a .dat file that will be the input to tachyon. you can
edit the file, which has the keyword Resolution in the second line.
now you need to manually re-run tachyon (easiest by adapting
the command line from the render menu). you may want to try out
playing with the availble parameters (-fullshade, -aasamples)
to see whether you like those image more...

regards,
    axel.

povray should actually be able to create TGA and TIFF files, IIRC
please check out the manpage/online help for the corresponding
flag (i though +FT should create .tga format files...), see:

  F[x] = write output file (in format x)
            FC - Compressed Targa with 24 or 32 bpp
            FN[n] - PNG (n bits/color, n = 5 to 16, default is 8)
            FP - PPM
            FS - System specific
            FT - Uncompressed Targa with 24 or 32 bpp
