Yes, TIFs are standard for printing and in the graphic design world. They are larger because they do not compress when saved, like JPGs do (which is why you shouldn't save your JPGs over and over...each time you do it throws out a little data...too many times and eventually it will start to look degraded, like JPGs saved at very low quality). For scrapbooking and using today's inkjet printers, it isn't too big a deal to work with JPGs, even when printing. Your printer handles the conversion from RGB colorspace (which is based on light) to CMYK colorspace (based on ink) and prints mostly fine. If it were a graphic design job, it would have to be CMYK TIFs before it could go to print, because you can't get color seps from a JPG file. (When you have a LO being published by a mag, they are converting the file or scan to CMYK before they go to print).
Concerning resolution, 300 is the most you would ever need (except in certain rare instances), it supports 150 line screen which is very high-quality. However, if you intend to scale the image larger, than you WOULD need additional dpi to ensure that when it is scaled, it is still high enough. I always and only scan at 300 dpi, but at about an 8x10 size. That way I can always scale down if necessary, but know I have enough dpi for most print jobs. If I needed larger, I would rescan to the appropriate size, again, at 300 dpi.
