The Sun (Surya) and Moon (Chandra) are always in Direct motion (Margi). They never go Retrograde. On the other hand, Rahu and Ketu are almost always Retrograde and never move in Direct motion.

No. Rahu and Ketu are Shadow Planets (Chaya Graha) and do not have a physical body to reflect light. Therefore, the concept of being "burnt" by the Sun does not apply to them. They are never considered Combust.

Shool means "Spike" or "Pain." It is generally considered an inauspicious yoga. It can cause physical pain or obstacles. It is advised to avoid starting conflicts or legal battles during this yoga.

Seasonal fruits, sweets (especially Laddu), and Panchamrit are standard. Since it is Magha month, offering items made of Sesame (Til) or Jaggery is also considered auspicious.
