Considering you've had at least a little experience with programming, perhaps try something a little more challenging than BASIC considering you already understand the basics of what a language actually does? It'll be harder, but the benefits are greater once you move on to a better language. BASIC is really only good for absolute beginners to teach them the simple things really. You can use it for more, but it's annoying and unwieldy in my opinion.
May I suggest C# or Python? C# is more like Microsoft's version of Java and is a part of the .Net suite like Visual Basic, whereas Python isn't made by Microsoft, but it's VERY simple and VERY useful (a huge amount of Battlefield 2 was written in Python if I recall correctly). Python would be much simpler for someone who's only had experience with BASIC, whereas C# would help you dive in to C-based languages. It's really a matter of how much you want to challenge yourself. I can tell you now that there's great benefit in knowing either, though. Python is awesome when used well.
I can't help you personally. While I do have holidays coming up I want to catch up on study I've missed, maybe work on one of my own projects, as well as maintain my commitment to the composition and playing of music (which I've been neglecting as of late). So basically when I'm not playing Minecraft or something like that I'll be busy, sorry bud ^_^;;.
I'll give you a couple of links to get you started though. Even if you don't have a dedicated tutor there's plenty of resources online to get you going for either language. C# .Net is maintained by Microsoft and thus has a lot of support, and Python has a well-written documentation as well as a very helpful community to dive in to. I'm not going to push you either way really. Just take a choice and go with it really. C# DOES rely on the .Net framework though, whereas Python essentially has the ability to execute on just about any operating system, and executes very fast and efficiently at that.

For some reason I remember the 2.x versions being more popular for different things. Probably not as much support for the 3.x versions yet. Just choose one and go with it. It'll be easy to switch between the two once you get the gist anyway.

If you're insistent on Visual Basic, you can find information about it as well as tutorials etc. on MSDN, the same place as C#.
Sorry I can't be of much more help, and good luck.
