Tablets are fairly expensive, so you might want to make sure you're proficient at programs like Photoshop so that it won't be a wasted investment. If you're spending that kind of money, you want to make sure you use the item to its fullest potential.
That being said, tablets are really useful, once you get they hang of them. They DO have a fairly steep learning curve. It's a very different feel to be looking at the screen, and be drawing somewhere else. Some people have a lot of trouble with the disconnect between the two ideas.
The solution to that is a
Cintiq (what I'm saving up for), but if you had the money for one of those, you wouldn't be debating a tablet.
Anyway... your questions...
1. Is it really worth to buy one?
Just for TB textures? IMO, no. If you plan to use it for other things, possibly.
2. What are advantages and drawbacks?
Advantages- More precision, easier flow of lines, more hand rendered feel to images.
Drawbacks- Cost, learning curve, limited applications for someone like you.
3. How can it help me in making textures?
mostly in the line of detail adjusting, and freeform objects. Making geometric textures, a pen won't be that much use, but if you're looking for organic, biomorphic, and natural shapes a tablet is great. Also, coloring can be really dynamic while using a tablet.
If I had to recommend that you do something, check with your school. Sometimes art departments have one or two that they're let you try out. My school has a few graphic design related courses, so we have almost 30 tablets. (I don't ever use them for TB textures though)
But you really should see if you can try it out first... they're expensive, and if you find out that you don't really like it, that would be a lot of $ down the drain.
