Welcome....... your question is a little vague....and i can tell you do not know much about satellite internet with exede.
You have specific questions, we can help you. But I SERIOUSLY recommend using the forums search....type in a short question and review what comes up..... tons of info on the site..... do some searching.
The problem isn't the time you spend on the Internet, it is the amount of data you consume. As Kaotic pointed out, there is a lot of material here an at Exede's webpage on how to manage your data usage more efficiently. Sadly, it is one of the major drawbacks of satellite Internet. The pipe is only so big.
