As far as random photos go you will want to check the copyrights surounding them so as to avoid being involved in any legal disputes.
Depends on your design/logos, if you are serious you could buy a screen printer and make your own screens they aren't that hard.
Digital printing you would have to find out about that somewhere else.
If you got digital copies of designs throw em up and get some opinions.
I one thought about it but couldn't be arsed with all the hastle. You will also need to consider a brand of t-shirts to use when starting.
