Assalaamu Alaikum
I want to know what are the:
a) greatest Suras
b) greatest Ayats
c) best times for Ibadat (of all kinds) in a Islamic year?

This is all I can think of- Suras Fatiha, Falaq, Naas, AYatul Kursi, Ramzan, first 10 days of Zilhaj.

About Al Baqarah and Ayatul Khursi:

Sayyidina Abu Huraira (RA) reported that Allah’s Messenger (SAW) said, “Everything has
a hump and the hump of the Quran is surah al-Baqarah. There is a verse in it that is the
chief of all verses of the Qur’an, the ayat ul-Kursi.”
(Tirmidhi 2887)


Surah Al Kahf:

Sayyidina Bara (RA) reported that while a man was reciting surah al-Kahf, he observed
his animal jump. He looked and indeed, something like a cloud was near. He went to
Allah’s Messenger (SAW) and mentioned that to him. He said, “This is sakinah
(tranquility) that descends with the Qur’an or descends on the Qur’an.”
[Bukhari 3614,Muslim 895,Ahmed 18534]

from Abu Sa`id (Allah be pleased with him), "Whoever recites Surat al-Kahf on Friday,
light shall shine forth for him between the two Fridays."
[Ibn Hajar, Talkhis al-Habir]


Suratul Yasin, heart of Quran:

Sayyidina Anas (RA) reported that Allah’s Messenger (SAW) said, “There is a heart for
everything and the heart of the Quran is Yasin. And, if anyone recites Yasin, Allah
records for him against his recital of it a recital of the Quran ten times.”
[Tirmidhi 2896]



Reciting Suratul Dhukhan at night equals dua of 70,000 angels:

Sayyidina Abu Huraira (RA) reported that Allah’s Messenger (SAW) said, “If anyone
recites surah Haa Meem ad-Dukhan in the night he will see the morning while seventy
thousand angels seek forgiveness for him.”
[Tirmidhi 2897]

Suratul Mulk protects from Punishement of grave:

Sayyidina Ibn Abbas (RA) reported that one of the companions of the Prophet (SAW)
pitched a tent on a grave. He did not know that there was grave. It was the grave of
human beings, who recited surah al-Mulk (#67) to the end of it. He came to the Prophet
(SAW) and said, “O Messenger of Allah (SAW), I pitched my tent over a grave without
knowing that it was a grave. The man inside recited surah al-Mulk to its end.” The
Prophet (SAW) said, “It is the rescuer. It rescues from punisment of the grave.”
[Tirmidhi 2899]

Suratul Waqia protects from poverty:

The Prophet(saw)said, ‘Whoever recites surah al Waqiah at night would never encounter poverty’
[Ibn Sunni 620]
VERSES


Last 2 verses of Al Baqarah (Amana rasoolu):

Sayyidina Abu Mas’ud Ansari (RA) reported that Allah’s Messenger (SAW) said, “If
anyone recites the two verses at the conclusion of surah al-Baqarah in the night then
that enough for him.”
[Bukhari 4008,Muslim 808,Ahmed 17067]

1st 3 verses of Al Kahf protects from Dajjal:

Sayyidina Abu Darda (RA) reported that the Prophet (SAW) said, “If anyone recites the
first three verses of surah al-Kahf then he is protected from the fitnah of the dajjal.”
[Muslim 809,Abu Dawud 4323,Ahmed 21771]

Imam Ghazzali has mentioned in his Ihya ulmuddin, 15 nights and 19 days of excellence for Ibadah:

[SusanSazzios]

Also I have heard,
Imam Shafi'i says in his book Al Umm that 5 nights are of great importance:
1. Friday night,
2. night of Eid ul adha,
3. night of Eid ul Fitr,
4. night of Rajab 1st,
5. night of Sha'abaan 15th.

[movlabc]

I am assuming that all the nights mentioned above^ refers to the night before the day
E.g- night of Asura -> night before Asura-day

Jazakallah Khair.

[RuttyUttepe]

Your assumption is right...
