For online study and Bible reading, go to blueletterbible.org I'm amazed at how many translations and study aides they have. You can also listen to the Bible whether by earbuds or reading along. But I'll say this one thing, if one listens to the Bible one can get through it faster in merely months. And it's all for free. But if one feels so inclined, they accept donations in which I send a few here and there.
If you want to study a particular topic in the Bible, such as the history of the Empires in Daniel's day, you can not only go to Blue Letter but also just do a general Internet search (make sure its a reputable site) and use the two together.
If you want software on your computer, you can try what the others suggested, but then compare that to the method I stated (which is all free). You may find that paying for software is not worth it. Software has its limitations, even with updates, and at best there may be links on that software to the Internet anyways. IMO software was better in the days of our first computers which is still better than having many books, but before the Internet really took off.
