Ok - I'm a little confused by SPF records.  So - help me out :)

Let's say I set up a pretty strict set of SPF rules on my domain.  Will that have any impact upon my ability to send mail from various locations via thundbird, outlook, etc?

I wouldn't think so, correct?  Or - am I wrong?  Would a fairly strict set of SPF rules confine me to only being able to send mail from specific locations via a normal email client?

SPF records only affect the server listed in the domain as the mail exchanger (MX).

The mail server does the sending and receiving, your client just bounces off of it (SMTP out)  or receives from it (POP IMAP etc in), so it is still only seen as coming from the mail server's ip address, which is used in the MX record and SPF rules apply.

So correct, it would not have any impact on your ability to send mail from various locations.

So - for the purposes of explaining it to my client...

Messages sent via Outlook/Thunderbird are actually seen by the server as being generated from it's own IP address due to login.  Therefore they are unaffected.

SPF records records, essentially then, are a list of mail exchanges that may send email with that domain name.
