A noncreature permanent that turns into a creature can attack, and its {T} abilities can be activated, only if its controller has continuously controlled that permanent since the beginning of their most recent turn. It doesn’t matter how long the permanent has been a creature.

If an Equipment attached to a creature becomes a creature, it becomes unattached. An Equipment that is also a creature can’t equip another creature.

If the noncreature artifact had any other supertypes, types, or subtypes, it will keep those. In most cases, the artifact creature won’t have any creature types.

Multiple instances of deathtouch or lifelink on the same creature are redundant.
