Digital BW, The Print

I am very new to B&W digital printing and am glad to find this newsgroup.
However I am having a difficult time with all the acronyms, etc.  Maybe I
could get some help.
I am presently using the following:
Windows XP
Paint Shop Pro 7.0
Epson 2450 scanner for 2 \ufffd X 2 \ufffd negatives w/Epson Twain
HP PhotoSmart P1000 printer
Hasselblad 500C/M camera w/100ASA Ilford film
I am making primarily 8X8 prints on Epson glossy paper.  I scan negatives
with the 2450 at 2400dpi, and print at 300dpi.  When I don\ufffdt use the unsharp
mask the prints are not very sharp. (It makes me wonder why I don\ufffdt just
replace the Hasselblad with a box of Quaker Oats with a pinhole.)  With the
unsharp mask the prints are pretty good.
Here are my questions:
1.	What book should I get to learn all the acronyms/processes that are being
discussed here?
2.	What parts of my process should I change to improve my prints, in order
of importance?  I will eventually want to make larger prints.
I would really appreciate any suggestions.
