Fowler offers the following hints and tips (without the examples!):
the four basic usages of shall and should as against will and would:
1:plain future or conditional statements and questions in the first person should have shall, should, not will; would.
2:the verbs like, prefer, care , be glad, be inclined, etc. are very common in first-person conditional statements. In these should, not would is the right form
3:in clauses of indefinite future time, and indefinite relative clauses in future time, will is entirely unidiomatic, either shall is used, chiefly in formal contexts, or, much more often, futurity is allowed to be inferred from context and a present is used.
4: that-clauses after intend, intention, desire, demand, be anxious, etc all have shall and should for all persons. Among the etc.s are not included hope, anticipate and the like; but the drawing of the line is not easy ; roughly, shall and should are used when the word on which the that-clause depends expresses an influence that affects the result, as a demand does, but a hope or a fear does not; a serviceable illustration is expect; mistresses expect (i.e. demand) that their maids SHALL wear caps; but we expect (i.e. are of opinion) that tomorrow WILL be fine.
of course, he refers to the OED as having the definitive rules, and to one of it's writers saying that the use of 'will' in place of 'shall' is an Irish, Scottish, or extra-British usage, which may ameliorate the possible damage....
