Translation of Marmaduke Pickthall and Abdullah Yusuf Ali, these are classical english translation.
you can refer to Dr. Hilali and Muhammad Muhsin Khan translation, this is one of the easiest and simple translation.
All of the three, you can find in internet as soft copy or if you just type order a Quran translation, you can easily have some link to order online and it is not that expensive even.
but i'll suggest you to have the Yusuf Ali translation, because it has a very good index system (you can find by letters and word), that will help you, and also it contains short but good footnotes with explanation also quoting from old and new testaments.
if you are not yet muslim, you can even have copies of Quran for free, they will deliver it to your door end, without any charge.
