1) If your lease, whether oral or written, requires all the rent to be paid by a certain date, if you don't pay in full by that date each month, you could be evicted. It doesn't matter if you're providing post-dated checks (since post-dated checks do not count as payment until their date comes around) or that you are doing everything you can--if you're making payment in full on time, you could be evicted. That does not mean the landlord cannot agree to take payment as you indicate--but it's the landlord's choice whether to do so.2) If you are on a month-to-month lease, you need only provide 30 days notice.
