I am running mc cable from a 120v. panel to a recepticle. The panel has no bottom plate. It patrudes through a raised floor with a skirted cover.
Does the mc need to be connected?
Does the mc need to be bonded at both ends?

What's a "branch circuit panel"?

I haven't heard that phrase before.

A lighting and appliance branch circuit panelboard.

The OP makes it sound like he is taking a circuit from a distribution panelboard. Either that, or the original installer attached a piece of wireway to the bottom of a L&A panelboard.

314.17 Metal Boxes and Conduit Bodies.
...Where raceway or cable is installed with metal boxes or conduit bodies, the raceway or cable shall be secured to such boxes and conduit bodies.

312.5(C) Cables.
Where cable is used, each cable shall be secured to the cabinet, cutout box, or meter socket enclosure.

330.40 Boxes and Fittings.
(this section requires listed fittings)

If you follow these requirements, you will have bonded the sheathing of MC cables.

408.34 Classification of Panelboards.
Panelboards shall be classified for the purposes of this article as either lighting and appliance branch-circuit panelboards or power panelboards, based on their content. A lighting and appliance branch circuit is a branch circuit that has a connection to the neutral of the panelboard and that has overcurrent protection of 30 amperes or less in one or more conductors.
(A) Lighting and Appliance Branch-Circuit Panelboard. A lighting and appliance branch-circuit panelboard is one having more than 10 percent of its overcurrent devices protecting lighting and appliance branch circuits.
(B) Power Panelboard. A power panelboard is one having 10 percent or fewer of its overcurrent devices protecting lighting and appliance branch circuits.
