The only thing im still unsure about is if I have 6 cogs on the rear wheel do I need A derailleur made for six speeds or are they universal between 5,6,7,8,etc.

Here is an example of a derailleur on ebay.

It doesnt state the number of speeds it willl work for. I just dont understand how a derailleur made to work with 9 rear cogs won't go into the spokes on a bike with 6 rear cogs.

Short cage will work. Shimano road rear derailers will work - even though the new ones are spec'd at 27T max, they will run on a 28T. I've even run mine on a 30T.

Speeds don't matter. You can use any Shimano SIS rear derailer EXCEPT Dura-ace 740x
