Hi ta00129,
It's a question we see quite often in the forum, but to be honest it's a little too general to really cover effectively.
Has Satya has suggested, check out the educational information to get you started, from there you can start developing specific questions in areas that you need help in.
Once you know the right questions to ask, then you will have a far better chance of getting a well informed response that is targeted directly to the area that is giving you most problems.
Don't be too concerned about asking too many questions, that's what we're here for, ask away. You'll also find plenty of other helpful members who are happy to chip in with their opinion and valuable experience as well.
