I am trying to teach myself Hebrew, I'm using Basics of Biblical Hebrew. Reason I chose this book is that it is simple enough to follow, has a workbook that you can work through. There are also free videos at i tunes university, these are by the American Memorite Biblical Seminary. Also the book is available in Accordance. Other Books available in Acordance are Ross, Introducing Biblical Hebrew. There are videos (free) available on the web. The most pain free way is to use the first Hebrew primer also in Accordance. This has embeded audio files.
Greek. Don't know, learnt Greek in the 1980s. I suppose, Basics of Biblical Greek is current, and the book is available in Acordance. There are a host of helps keyed to this book, so might be a good place to start
This all depends on what your target is. Is your aim to know enough to get around the text or to read most things in the original languages.
Can I ask a question
Do you pick up languages easily?
If not, set yourself a lower target, get to that point first and then raise the bar a bit
Hope this helps
