Yes, most recent card readers support SDHC. Your computer doesn't care,
it's all handled at the card reader level.

Depends a lot on camera... If you have a compact which only produces
Jpeg and won't do burst shots, then the slower cards will do. If your
camera can use "raw" format or burst shooting (and even more if it's
both at the same time), then card speed is important, and will impact
burst rate/length or delay between pictures (for raw mode). My camera is
slowed by cards under 9MB/s. Using a better card doesn't make the camera
any faster, but it makes the picture transfer to the PC a lot quicker
when using a card reader.
