Wills and Estates

Can a person leave property in their Will to a revocable trust in Florida?
My Father made a revocable trust in 1999 and later made a Will. In his Will it states that the farm goes to the trust to be handed in accordance with the terms of the trust. Is this legal?
Can a separate list of items and who is to receive them be valid in Florida after death of the maker?
My Grandmother made a Will and when it was read my Mother said it referred to a separate list of her personal property that listed who was to receive certain things. Today I found the list in her bible. Is this list valid in Florida?
Did execution of a codicil referring to a 1980 Will revive the 1980 Will in Florida?
My Father made a Will in 1980 but later signed a written revocation. In 1990 he made what is called a codicil which I understand is a change to the Will and made reference to the 1980 Will in the codicil. Did the codicil make the 1980 will valid even though it had been revoked. We are in Florida.
