Bear with the noob-ness of this question, but what does the 11-34t or 11-32t or 11-28 t mean? I am looking to buy a new cassette, I know i have to buy a 9 speed , but do I have to replace my Shimano HG30, 9-speed, 11-34t. with an 11-34t alternative?

11 is the smallest cog and 34 is the largest cog.

There are lots of choices for 11-34t cassettes from Shimano and SRAM. Both work equally well. Paying more gets you lighter and often a nicer finish but not necessarily more durable. Make sure to replace your chain at the same time if you haven't already.
