I assume your saw takes a 10" blade, in which case you should buy a good quality blade with 24T, or maybe up to 36T if you are only ripping thin stock. The fewer teethmean that the gullets are bigger and can carry away all the sawdust. Many teeth mean that those gullets are too small and get clogged. Even if the blade is new and sharp it will still give poor results.
As regards the fence - for ripping, you should fit a short fence so that the far end extends just beyond the first teeth, but not as far as TDC of the blade. Depending on the rise & fall mechanism of your saw that might mean that you have to adjust its position slightly for different depths of cut.
For cross-cutting you should not be using the fence at all and for cutting sheet materials like MDF you can use the full-length fence.
There is a video of why the short fence is important here:

I have since made an updated version of the short fence, which includes tool storage, which is on one of my DVDs. I forget which; WE8 probably, though I'd have to check.
I don't mean this nastily, not at all, but it seems to me that you are putting yourself at unnecessary risk. Tablesaws bite if you ask them to do something for which they are not designed. I learned my lesson very early on, and got away lightly, but others are not so lucky.
