When researching an invention, you will often need to read existing patent applications to make sure your idea is new. Patents can have many pages and horrible wording, but in general it is only the first major claim of a patent that is critically important. The rest will simply be a smaller claim than the patent can appeal in case the patent examiner revokes or rejects the highest claims.
Where there might be ambiguity in a claim, the description of the patent may influence the claims and, therefore, may have been deliberately written as such, so check the description to see if it tries to provide it.
Patent claims are not exclusive. The fact that a claim describes a way of doing something does not imply that it can not be done otherwise.

The patents include a detailed description which, in general, is intended to provide an explanation / instructions on how the invention could be used. Keep in mind that this only has to cover a specific use of the invention and does not exclude claims that are used in other ways.
The claims generally refer to an Apparatus (equipment designed or assembled for a particular purpose) or a Method (a way of doing something), and often the patents include both with the intention that the claims of the method can be rejected if the claims of the device are rejected.
Interestingly, one of the objectives of patents is to promote invention and innovation. While preventing other companies from copying ideas can do the exact opposite, the natural reaction to a patent is to try to solve it. We have worked with several companies and we have done exactly this, having been informed about the product they want to produce and the existing patent that seems to block it. There is almost always a way around a patent, but the goal is to try it in a way that leaves you with a commercial product that still serves your purpose in an affordable way (big patents block this by protecting against all economic ways of achieving the same).

It does not make sense to give the patent attorney too much information. They need to write the patent based on their knowledge and experience, not their wrong attempt. This is what should ideally be provided:
- Drawings and descriptions of the drawings to convey the idea.
- The advantages of the invention.
- Modifications that are possible for the invention.
- Crucial points and optional points.
- Do not include many existing patents; they will only have to read them and, therefore, they will cost more. One or two could be useful, however.
