Gerunds, infinitives, and participles are types of verbals, which are words formed from verbs. Gerunds function as nouns, infinitives function as nouns, adjectives, or adverbs, and participles function as adjectives.

The FINAL syllable is always stressed in Spanish infinitives.
Unlike the case of split infinitives, I think it is acceptable to interpose the word always within the present perfect, e.g. "She has always been fond of chocolate." I checked one supposed English reference and saw this usage.

No, not all words that end in -ar, -er, and -ir are infinitives. Infinitives are the base form of a verb, usually preceded by "to." For example, "to sing" is an infinitive. These endings can also be found in various verb conjugations in different tenses and moods.
Infinitives can be used as subjects of sentences, objects of verbs, complements of certain verbs, and in sentences to show purpose or intention.
Because so many people consider split infinitives acceptable, it's OK to use them in business writing.
Split infinitives make awkward speech and should be avoided. If one infinitive is split, creating another one will not correct the structure. Using the proper form in all infinitives is the best way to fix structure.
