When first starting out it can be overwhelming! The good news is there is lots of great info here on the Community Forums that you can search and learn from.
If after searching, you still have questions, create a list and then post one question at a time in the most appropriate forum. Start here for Tips on Asking Questions. You'll then get answers from folks willing to help!
So search first, then post where you still need help. Be sure to include as much detail as possible so that you can get the most specific answers you need!
