36 bit scanners are fine, You won't need higher than that unless you want to send your artwork to professional printer. Scan at 72 DPI for online as monitors can't display more than that. For printing higher the dpi better. SO any scanner supporting upto 600 dpi is fine
Go for a flatbed scanner. Not a pass through scanner as you can't scan a bound book in that. You need seperate pages for pass through scanner.
Make sure you computer supports its port (parallel or USB)
I would not spend more that $20-$30 on scanner if you need just for hobby. I bought one for $20 (after mail in rebate, $40 before rebate in staples) 2 years back in december and it is great (slimscan E3). Look for deals this time of the year and you will find one in this range. I had even seen one at $10 after thanksgiving day but was gone before I reached the store.
Also I would not buy it online as at that price it is not worth if you have to return it etc.

I have both, Paraller and USB. USB is much faster than paraller. Keep on checking local stores of Staples, Office Depot, Offce Max, Best Buy, Circuit City. Generally, Staples give very good deals. I bought USB Flatbed for $15 ( and all my office collegues also bought it ). As Ajay said for hobby these kind of scanners are ok.

Arch : Found some information on BITS and resolution.
BITS : It is actually Bit Depth. For each pixel, the scanner remembers 8 bits of information for each of three colour levels (red, blue and green). The higher the bit depth, the better the scanner is at distinguishing between really close shades of the same colour. This results in higher image quality. . If you plan on getting a scanner for slides, negatives or transparencies you need at least 30 bits, and 36 bits would be preferable. Now you might be wondering what happens if you get a scanner with 30 bits, but your monitor or printer can only handle 24 bits of colour data. The extra information at higher bit depth will still produce smoother colour gradations and better overall image reproduction.
Resolution : There are two types of resolution, optical and interpolated; the first is the most important. The optical resolution of a scanner is measured in dots or pixels per inch (dpi or ppi). More pixels mean better resolution and sharper image quality. The number of pixels a scanner can generate is based on how many CCDs are arranged horizontally and vertically in the scan head. Remember one CCD produces one pixel. Resolution is quoted both horizontally and vertically (eg. 600x300). When comparing resolutions always use the smaller number. If you need to pick up fine details, small fonts or complex lines or edges you'll want more optical resolution.
The interpolated resolution for a scanner is always higher than its optical resolution. To get interpolated resolution the scanner takes the information from two true pixels and using mathematical algorithms fills in a third pixel between them. Since more pixels are being mathematically generated the interpolated resolution is higher. Optical resolution is a more reliable indicator of image quality so don't be fooled into mistaking interpolated resolution for optical resolution. Higher interpolated resolution will be sufficient if you just need to enlarge images.
An optical resolution of 300 dpi should be enough for the average user. It will produce an image that will look good on the web or printed out on an inkjet or laser printer. Graphic artists who want to scan line art or images with lots of detail will want to go up to 600 dpi. Only people who are looking to buy a scanner for slides, negatives or transparencies need 1200 dpi resolution. Such a high resolution is needed to compensate for the small size of the original.
Company : I do not think it will make any difference. Generally, scanners work on CCD ( Charges Couple Technology ) which is used in most of the scanners.
Speed : USB is faster than paraller.
