Regarding - “The one who recites it after each of the obligatory prayers, then death will be the only thing [i.e. barrier] preventing him from entering al-Jannah .”
This hadeeth is reported by At-Tabaraani, ibn as-Sunni, ibn Hibbaan, and others. Ibn Hibbaan graded it as saheeh in his book As-Salaat. Al-Haythami said: “At-Tabaraani reported it in Al-Kabeer and Al-Awsat with different narrations, one of them is good.” Al-Haafith ibn Hajar said,“Its isnaad is saheeh...and ibnul Jawzee was inattentive when he reported it in his Mawdoo’aat (fabricated collection of ahaadeeth).” Shaykh al-Albaani authenticated it in As-Silsilah As-Saheehah (vol.2, no.972) and said: “Ibn Khatheer declared it as saheeh in his tafseer (exegesis).” He noted that Shaykh-ul-Islaam ibn Taymeeyah’s calssification of this hadeeth as weak, as in his Fatawaa (22:508), “Appears to be made at the stage when he was beginning to seek knowledge. In fact, his student Imaam ibnul Qayyim related that he (ibn Taymeeyah ) was reported to have said, “I never relinquished [to recite] it after each [obligatory] salaat.” After detailing the various reports regarding this hadeeth, ibnul Qayyim commented, “It has its basis and it is not mawdoo’ (fabricated).” [See ibnul Qayyim’s Zaadul Ma’aad (Beirut, Lebanon: Mu’assasatur-Risaalah (Checked by Shu’ayeb and ‘Abdul Qaadir al-Arna’oot), 2d, ed. 1418/1997)], pp. 293-294.

And regarding - "whoever recites it at night [before going to bed], Allaah will appoint a guard for him and stay with him to protect him all night long, and no shaytaan will come near him till morning"
This came in the famous hadeeth reported by al-Bukhaari in his Saheeh and which the Prophet (r) assigned Abu Hurayrah (t) to be in charge of the Zakaat revenue of the month of Ramadaan. Someone started to steal some of the foodstuff. When Abu Hurayrah (t) took hold of him and threatened to take him to the Prophet (r), he said: “I am needy and have many dependents, and I am in great need.” Abu Hurayrah released him and told the Prophet (r) of what happened. He (r) said, “Indeed, he told you a lie and he will be coming again.” Knowing that the Prophet (r) says nothing but the truth, Abu Hurayrah waited for him watchfully. He caught him trying to steal again. He threatened him to take him to the Prophet (r) but then released him when he complained of his great need and promised not to come again. The Prophet (r) told Abu Hurayrah, “Verily, he told you a lie and he will return.” He returned and was caught stealing for the third time. This time, however, he told Abu Hurayrah (t), “I will teach you some words with which Allaah will benefit you.” I asked, “What are they?” He replied: “Whenever you go to bed, recite aayatul-kursi:
{ الله لا إله إلاَّ هوَ الحيُّ القَيُّوم }
till you finish the whole verse. (If you do so), Allaah will appoint a guard for you who will stay with you and no shaytaan will come near you till morning.” Upon telling the Prophet (r) of this, he said: “He really spoke the truth, although he is [absolutely] a liar. Do you know whom you were talking to, these three nights, O Abu Hurayrah ?” Aboo Hurayrah said, “No.” He (r) said, “It was a shaytaan.” [See Saheeh Al-Bukhaari (Arabic/English), vol. 3, no. 504].
