The truth is........crap in, crap out.

If you have a bad video source,the best you can do is try to make something just as, or almost as, bad. If you are really doing your encodes with a max rate of 9000 and max average of 5000, you are in a sense just duplicating the original MPEG-2 stream. If you do the above settings (probably should include bicubic c value of 0.60) you will definitely notice a softening effect.

However, softening may be no more pleasing to the eye and in fact you may notice other artifacts/distortion that may be worse. Think about Dolby B noise reduction on your old audio cassettes. Was that any better than some hiss?

Rip a chapter, play with the Bicubic, noise reduction and TemporalSmooth settings. Place each test as a chapter on a SVCD and compare on whatever equipment you use to see which is best.

Again, crap in, crap out.
