Yes I don't believe there is any rule governing the ball return lift placement, I believe that is because it's in a non play area it's between the approaches.
You need to look at the USBC Equipment and Specification Manual

Yes they do.Approach length also had no specs they need to follow. They can be 10 feet or 25 feet or whatever, it doesn't matter.
USBC Equipment and Specifications Manual
Approach
Extending from and exclusive of the foul line there shall be an unobstructed level appraoch
which shall be:
1. Not less than 15 feet in length.
2. Free from depressions exceeding 1/4 inch.
3. Not less than the width of the lane.
Yes while not required. There are spec's governing those marking and there is a max. number of them there can be.Dots on the approach... There is no specs for how many you have and they actually aren't required to have any at all.
There is no measured standard for how far from the foul line they have to be either.
Also, it's not a requirement for them to have 7 arrows on the lane. Some apparently have only 5? I know of one place that had none. Again, not required. We all know of course know about range finders. They definitely aren't required and it's a manufacturer thing. AMF typically don't use them but Brunswick does. With synthetic that doesn't always hold true these days. With wood it 100% did. Again, not required.
Lane and Approach Markings or Designs
Lane and approach markings shall only be permitted in accordance with the following specifica-
tions:
1. Measured from the foul line, a maximum of seven guides may be embedded in or stamped
on the approach at each of the following points: 2-6 inches; 3-4 feet; 6-7 feet; 9-10 feet;
11-12 feet; and 14-15 feet. Each series of guides shall be parallel to the foul line and each
guide shall be circular in shape and shall not exceed ¾ inch in diameter.
2. At a point 6-8 feet beyond the foul line and parallel thereto, there may be embedded in
or stamped on the lane a maximum of 10 guides. Each guide shall be uniform, circular in
shape, and shall not exceed ¾ inch in diameter.
3. At a point 12-16 feet beyond the foul line, there may be embedded in or stamped on the
lane a maximum of seven targets. Each of the targets shall be uniform and may consist of
one or more dowels, darts, diamond, triangles, or rectangular designs. The overall surface
covered by each target shall not be more than 1¼ inches in width and six inches in length.
Each target must be equidistant from one another and set in a uniform pattern.
4. At a point 33-44 feet beyond the foul line, there may be a maximum of four targets. Each
target must be uniform in appearance and shall not be wider than a single board or longer
than 36 inches.
5. Embedded markings or designs shall be of wood, fiber or plastic and shall be flush and level
with the surface of the lanes and approaches.
6. When the markings are stamped on wood lanes, they shall be applied to the bare wood and
then covered with lacquer, urethane, or similar liquid transparent material generally used in
resurfacing. All such installations in any one center shall be uniform as to design and mea-
surements and at least on natural pairs of lanes.
7. Glow/Cosmic bowling may only be certified on lanes that meet all of the specifications listed
under Lane and Approach Markings or Designs.
8. Glow/Cosmic lane designs must only be visible in glow conditions.
9. In an area within two inches, but not closer than one-half inch of the foul line, there may be
an advisory about crossing the foul line. The wording/lettering/symbols of the advisory may
be 1 to 1½ inches tall. The advisory shall run parallel to, and shall not extend more than
two inches from the edge of the foul line. The advisory must be first submitted to the USBC
Specifications Department for prior approval.
10. For certification process, a center shall have each lane numerically numbered and not dupli-
cated. The number may or may not be visible to the general public but must be easily seen
by the inspector, e.g. on the back side of the masking unit.
