The limbs of the korban tamid, before they were burned, were put on the lower ½ of the ramp on the westside. The limbs of the koban mussaf, before they were burned, were put on the lower ½ of the ramp on the eastside. The limbs of the korban Rosh Chodesh, before they were burned, were put below the karkov of the mizbaiach.

Shikalim and Bikurim applied only when there was a Bais Hamikdash. Masser of produce, maaser of animals, and bechoros [first borns] apply at all times.

If you set aside bikurim or shikalim as holy, they become holy even in our times. R’ Shimon says that is not true with bikurim as it does not apply at all in our times.
