Hi, Skyline,
As to your second point, I've run across both 'ing' verbs and infinitives after 'start', so either usage would be okay these days, I reckon.
When learning English at university, we used to learn by heart those verbs that should be followed with an 'ing' verb and with an infinitive. (I still have somewhere a list of such verbs devided in two columns, but I guess it's not too correct since it claimed 'start' should always take an 'ing' verb - but it's not quite so, as I've mentioned.)
By the way, when you use an 'ing' verb or an invinitive, there may be a difference in meanings:
He stopped to smoke. <-- He made a stop in order to smoke a cigarette.
He stopped smoking. <-- He gave up smoking.
