Well, as benissimus has said, you will find all the assistance you will need here so long as you’re willing to try. I’ve been doing the same thing that you are about to start, so I can give you a few helpful ideas to get you started. The good news is that it’s a fun part of the process.
First, download one of the beginner texts on this site. Here’s a link to the page: http://www.textkit.com/latin_grammar.php
I’m currently working with the “Latin for Beginner’s Book” by D’Ooge and others here are as well. But equally good is “Beginner’s Latin Book” by Collar and Daniell. If you aren’t sure, get them both (as some here do as well) and you can sample each or work with both. The books are written for someone who is just starting out learning Latin. They're free too!
Make sure you get the Adobe Reader from their web site. It’s free and you’ll need it to view the book on your computer. You can print out a few pages at a time or the whole book. Or you can work with it on the computer. If you’re comfortable with the computer and typing isn’t a chore, than I recommend using your favorite word processor to do your exercises. This will help a lot when you have questions you want to pose here because you can simply cut and paste. Otherwise a notebook will work just fine.
That will get you started with the texts. When you hit a rough spot, come back here and post your question to the “Learning Latin Forum” or “Latin for Beginner’s” forums. Also, read the various forums and the past discussions because many questions have been asked and answers given that you will find helpful along with solutions to exercises. There are answer keys available as well. When posting, state what book you are using, the question being asked , any Latin provided, and the problem you are having. That will be enough to get the ball rolling.
Now, you never mentioned why you are learning Latin. Are you taking a self study course? Reading the bible? Taking classics courses?
In any case, you’re in for a treat!
