I can read music, how well and how quickly depends how much I'm doing it at the time. I'm currently not reading much so I need to think about it and its slow. When I was a teenager I played clarinet in a youth orchestra and it was automatic.
Reading for guitar or piano is trickier than the clarinet because there's more than a single note at a time often, but it's all just practice.
Standard notation has so much more information in it than tab. Tab is great especially as it tells you where to play a specific note (out if three or four possible locations). But, it has made me lazy. Standard notation tells how long, how loud, what quality and a bunch of other things. But, you don't need to absorb that info all at once.
It's really not scary. It's just a doing thing. The more you do it the more automatic it becomes.
Learning how to read standard notation will open up a bunch if resources that you don't have access to now. Be open to it and it won't bite you.

Edit BTW, while I'm in apps promotion mode, once Neil has demystified standard music notation for us all, there are a bunch of tablet apps that will help you to practice recognising how notes are written on the music staff and where they are on the fretboard. I listed one in my recent iPad apps thread. But, there are a heap of them. Playing them of course is the only real way to get them into your muscle memory and brain longer-term. But, they can help.
