Well those would be used to discuss text A's form and structure as it is a transcript, so for the other two texts you'd need to consider the use of rhetorics, sentence types (Declarative, exclamatory, interrogative, imperative), humour, graphology (headings, paragraphs etc), word classes, imagery, grammar, representations of speech, high frequency lexis/low frequency based on audience of the piece, hyberboles, alliteration, repetition, stats/facts, quotes, professional opinions, pronouns to establish audience/purpose/point of view, bias within the piece...
This could all link into structure as structures of texts are based off the audience and so the language used in them helps to form the structure.
So say you have an advice article you'd find headings and bullet points, columns, subheadings, images perhaps. You'd establish this as graphology then analyse the role of each device/feature in helping to form a structure for the piece.
In contrast if you had a poem you'd talk about structure in terms of stanzas, placement of punctuation, length of each stanza, whether it rhymes etc.
Novel, you'd discuss the use of paragraphs - makes it appealing to readers, breaks down the information, big paragraphs suggest importance in terms of imagery etc...
I hope this is the answer you were after...sorry if it's not very helpful...
