1 rifle, 1 bayonette, 50 rounds and a spade. Standard issue. Bayonette's harder to use without the rifle as there's no grip on most of them, they are made to be attached to the rifle.
Depends entirely on when/where the bayonet is from. Early models often fitted down the barrel (think smooth bore muskets and early rifles here) and so had no handle. Pretty quickly they ring-mounted them to the barrel so you could still shoot (again, usually no proper handle). A little later they slotted on to the side and were basically large knives attached to the gun (in order to be multi-purpose - and hence had handles to be used as knives/short swords). Some of the more modern ones have reverted to a simple spike for stabbing things with little or no usable blade with the upside that you don't have a huge machete like thing (yes, some of the WWII German ones I have are VERY heavy chopping blades -the English ones I have from that period are lighter/thinner but still a pretty heavy duty foot long knife) attached to the end of your rifle cocking up your aim.
