Soory I'm slow responding. Somehow gnupic got edited out of my SPAM filter
files, so gnupic message were going to the SPAM heap. Bummer.

Yup.

Or building. Check out my TLVP/THVP programmers here:
http://www.finitesite.com/d3jsys
You can be up and running with a 16F877 or 16F628 type part in an afternoon
at very little cost.

That's gpasm's job.

There are a number of software programmers. I use a two level approach with
my 16F877 projects:
A) I use the TLVP/THVP programmer to dump a Wouter van OOijen's WLoader
bootloader into the part using picprg2.3d.
B) I then do in circuit development using Woj Zabolotny's linwload to interact
with the bootloader.
All of the software and procedures are outlined on my PIC page.

Close enough.

For the most part. All modern PIC parts.

Not really. It has the same problem as all assembly languages: not enough
abstraction. So while it's not hard to learn, you will find yourself getting
stuck in quite a bit of detail.

PIC assembly ;-)

Many. One I like is Nigel Goodwin's:
http://www.winpicprog.co.uk/pic_tutorial.htm
Because it specifically uses the 16F628 as opposed to the 16F84 that most do.
Another possibility is to take a look at a couple of high level languages
which may simplify entry to the game. One is Wouter's JAL:
http://www.voti.nl/jal
Only problem is that Wouter hasn't released a Linux version in a couple of
revisions. One that I took a brief look at but not done any development in
is Wayne C. Gramlich's uCL:
http://web.gramlich.net/projects/ucl/index.html
Which is quite intriguing because it's written in tcl (which means it will
run most anywhere), compiles down to PIC assembly, and is very very well
documented.
Hope this gives you some insight.
