/boot partition mislabeled on last reinstall - need advice on how to fix

[Claude Jones]

I did a fresh install of FC5 about three weeks ago. 
I have three drives in this machine, all SATA, which I set up 
under the custom partitioning option:

sda is 200GB
It was supposed to be: 
500 MB sda1 formatted as ext2 and mounted as  /boot
2 GB sda2 formatted as swap
the rest formatted as ext 3 and mounted as  /

sdb is 300 GB
sdb1 is formatted as ext3, takes up the whole drive, and is 
mounted as  /home

sdc is 500 GB 
formatted as ext3 and is mounted as /home/cj/archive

I just realized this is not what happened. 
sda1 got labelled as /boot1 and is not mounted
/boot is therefore mounted under / which is on sda3

I had some strange log messages for awhile reporting smart errors 
on sda - after running various diagnostics on it, I ended up 
running Spinrite on that drive for 18 hours, which found 
nothing - since then, the log errors have not reappeared

In the  course of trouble shooting those log reports, I discovered 
this issue with sda1 being mislabeled.
I'm pretty careful when partitioning, and I check and recheck 
things - I can't imagine I let a typo like that get past me, 
though anything is possible. 

So, my first question is, can anyone think of any thing that could 
have caused that to happen besides a typo? 

My second question is about strategy. I'd like to return /boot to 
sda1 - any suggestions on how to go about that would be 
appreciated. This whole area of how file systems get mounted has 
been changing over the past 6-12 months, and I'm having a hard 
time getting my brain wrapped around the best way to go about 
this.
