The non-doing of any evil, the performance of what's skillful, the cleansing of one's own mind: this is the teaching of the Awakened. •
No need to carry anything with you. Discard this fear and clinging, Mr/Mrs is able to remember that, and then there is all way to simply stay with that.

I recommend the book In The Buddha's Words by Bhikkhu Bodhi. It is an anthology or selection of translated suttas from the Pali canon. It is also thematically and systematically arranged. You can look at the Table of Contents on the Amazon page I linked. It is 512 pages long, which is quite alright.
If you want a free or online equivalent version of the book above, with the original Pali text accessible, please see this answer for an equivalent version.

You'd be hard pressed to find a single sutta that covers everything. The suttas really don't work that way. To compound your difficulty, you'd be even harder pressed to find an English/Pāli version of any text! If I had to pick one sutta from the original canon, however, I think I'd go with the Sāmaññaphala Sutta. It does an excellent job of providing a bird's eye view of the gradual training in the least amount of space. You can find the Pāli version of the text here. It's in the Tipiṭaka under the Suttapiṭaka, Dīga Nikāya, Sīlakkhandhavaggapāḷi, Sāmaññaphalasuttaṃ. (I'd appreciate if anyone can link that directly!) A bound copy is available here - but again, no Pāli. Bhikkhu Bodhi also did an excellent translation of the sutta and its commentaries. That's available here. If you are going to spend the money, go with his version.
There are other single, bound texts that are far more detailed, technical, and honestly, I'd say more helpful. Key among these is the lengthy Visuddhimagga written by Buddhaghosa. Seriously, that guy spares no expense on detail. I swear he thought he was getting paid by the word! It also meets your requirement in that it is written in the [supposed] language of the Buddha - Pāli. Mind, it was written several centuries after the Buddha's death. The original text is also available on tipitaka.org. It's under Anya, Visuddhimagga. A bound copy of this book weighs about five pounds. I'm not kidding. It's not something you'd want to carry around with you. A dual language version would be enormous!
