TV & Stand Size: The minimum width and depth of your TV stand is going to be determined by the TV that it will hold. Flat screen TVs are thin enough to work with just about any depth, but old CRT TVs will require a much deeper TV stand. With flat screen TVs the depth of your stand is determined by personal preference rather than requirements of the TV. Measure out the space on your wall, or compare against existing furniture to get a sense for the amount of space you want the stand to occupy.
The width of your TV stand will depend not just on the width of your TV, but also on whether you intend to display other decor on the stand, or use it as a place to set down keys or mail when you get home. At a minimum, a TV stand needs to be wider than the base of the TV - and for flat screen TVs that base is typically quite small, much smaller than the actual TV width. Many people prefer a TV stand that is substantially wider than the total width of a TV, leaving room for decor. Keep in mind that the stated TV dimensions are measuring diagonally from corner to corner - so a 46" TV is not actually 46" wide!
Height: The ideal height for a TV stand depends mostly on the kind of seating in the room where the TV will live, as well as the height of viewers. Low to the floor couches will call for shorter TV stands, while taller seating will need a equally tall stand. As a rule of thumb, the bottom third of the TV screen should be at eye level when viewers are seated. Also note if there will be any obstructions between seating and the screen - tall decor on a coffee table or multiple rows of seating could necessitate a taller TV stand.
Storage: In addition to supporting your TV and looking good, TV stands often double as useful storage. The most simple TV stands usually include at least a shelf to hold a DVD player and other electronics that are typically connected to a TV. But larger TV stands can include multiple shelves to store DVD collections, cabinets to conceal electronics, or drawers and other cubbies to provide convenient storage for the living room.

If they are in separate bores, yes you can replace them separately.
If you look at the edge of the door and you have one plate encompassing both latch and deadbolt, then more than likely you`ll have to replace the whole mortise box.
Although some have a screw through said plate that you can remove to release the cylinder, then check it with your key. If it works independently from the box, the problem is in the box and it should be replaced
