1) Yes, I think it makes sense to interpret it that way. 2) Since it means "all that the Stoke players are appealing for", and this is analogous in form to, say, "the decision that I am appealing for", I think you could argue that technically it is (provided you consider "appeal for" a verb, otherwise it is the object of the preposition "for"). However, unlike the case with "appealing for the decision", it does not actually seem possible to express any similar meaning using the words "appealing for all".
