Basu,
Unfortunately, you really can't take advantage of the lower book prices in India. There is no way for you to know what texts are required for any given class until you arrive in August. Sorry about that!
The Residence Life web page states that, "All beds on campus are twin extra-long and measure 36 inches x 80 inches." It's definitely a good idea to bring some sheets to campus, even though I believe international students are given an opportunity to shop at the local Linens n' Things before Orientation.
The International Students Association website has some great information for incoming students such as yourself. A fairly comprehensive list of jobs on campus is located here:
http://ww2.lafayette.edu/~isa/NewStudents.htm. As you can see, there are many options for students.
Work study jobs require students to work 8-10 hours per week, and one can earn anywhere from $1,000-$1,750 toward tuition over the course of an academic year. Jobs voluntarily taken on by students are very flexible...it all depends on how much a student is willing to work!
