Hi Emack2 and Welcome to The Forum.
First off, I've had some cracking times in Bournemouth when I was younger. For an old town it has it's young bits!! Next, remove your postcode from your "location". I've got it now so just let me know when you are away!!
Seriously though, yes all your pictures are compatible (well, depends on the format in reality). So, bite the bullet, if your pc supports 64 bit you won't look back.
Talking pictures, I spent a fortune on plug-ins that were 32bit and haven't been updated, unless I spend again. So I don't use 64bit Photoshop, but when I have used it, the differences were negligible, depends how fast you can make a coffee.
To take full advantage of 64bit, I'd suggest you fill in your system specs in your profile, that way you don't keep answering the same daft/ sensible questions.
And did I say Welcome? We need more Brits!!
For help with how to fill your specs see
How to get BSOD and crash debugging assistance. (You only need the top bit)
I personally hate seeing 6 or 7 people asking "what graphics?" fill that in and you can say "Open yer eyes yer blind bugger"!!
HTH
