Welcome to Texas and Cypress. While I am new to brewing and don't have another area to compare to I think you will be happy home brew wise here.
Cypress does not have a brew club yet that I know of but, there are a lot of brewers in Cypress.
South of Cypress is the Katy club.
I am a member of the Cane Island Alers. We had a monthly meeting last week with over 100 people in attendance. It was the annual crawfish boil but, normally the meetings host 30-40 people. They have a active facebook page.
North of Cypress is
The Kuykendahl Grain Brewers Club
http://thekgb.org/ I have not been to one of there club events but I have heard it is a good organization.
There are more clubs in Houston you might be interested in but they are farther away.
Defalcos is our oldest home brew store (I think). It has a good selection and has been in business for a good while. I have purchased supplies there and it was a good experience.

Texas Home Brewers is in Katy. It is my go to store because it is closer to Cypress, they have been very helpful and, have had everything I needed so far. They are celebrating their three year anniversary this weekend. If you are in town you should check it out for sure!

In Cypress you should check out RockWell Grill.

Wednesday night I am told is bottle swap night. You can bring your homebrew or other and swap with people. I have yet to make it to the event but I hear it is a good time. Rockwell has a great selection of local breweries draft beers.
I know we do have a good bit of beer competitions in the Houston area but, I am not yet at that level so, I can not tell you much about those.
Currently I am a extract brewer with specialty grains looking to transition to all grain. Feel free to contact me if you have any questions.
