Hi Singz and welcome!

Yes, water is very important when you follow a low carb way of eating...at least eight 8 oz. glasses a day, more if you can drink that much.
Take some time and browse through the board. As Angela suggested, there's LOTS of great information in those stickys at the top of the page. The recipe forum is also great for ideas and recipes as well as the journals of different members.
Consider starting a journal of your own. That is your own special space where you can post daily menus and just generally share whatever's on your mind. Other members can peek in and make suggestions and just generally give support there, too.
Always feel free to ask whenever you have a question. Usually someone comes along to answer you quickly.
Happy low carbing!
