Those tips seem way too high. To put those figures in perspective, legal minimum wage in Haryana (state next to Delhi and one of the richest in India) is 5,800 rupees/month, and there are plenty of unskilled workers (live-in maids etc) getting paid much less than that. If you tip somebody Rs. 1500/day for a month, he's making almost 10x that!
I'd revise those figures to something like this, but please bear in mind it's been a few years since I was in India and these may be on the low side by today's standards.
Local Guides: INR 200/day for a personal tour (on top of the agreed fee and only if he's done a good job, that is; don't fall into the common trap of "pay me what you like" and then being pestered for silly amounts at the end!)
< INR 50 for airport transfers
INR 100/day if it's just point A to B, wait around, and back again. Maybe 200 if he's driving you around all day. If he's overnighting, his accommodations should be accounted for in the base price; again, be sure to sort this out beforehand.
Hotel Porters: INR 50 per bag
Housekeepers: Hotels often have central tip boxes that get shared out to everyone, and ~5% of your bill is generous; if you want to tip the housekeeper alone, maybe INR 50/night?
