Put simply, is it possible?

I can't get a PS3 online due to having dial up, so my best bet is downloading them on PC.  But, is this possible?  Can I download them by PC, shove 'em on a USB stick and install them on the PC?

No doubt I could download them, as everything is on the internet somewhere.  But, as you've guessed by now, I don't know if they'd work on the PS3.

By downloads, I mean:
- Firmware updates
- Game updates
- Backwards compatibility software patches (included in firmware?)

Thanks!

Also, does anyone know of any good PS3 blogs/websites?  I don't want a fanboy/bias one though, or at least not ones that claim everything that isn't a PS3 is crap, those ones just piss me off.  I subscribe to quite a few RSS feeds, but most don't seem to have many PS3 posts.  Also, what about PS3 podcasts?  For both, an RSS feed is not essential, but HUGELY preferred.  In fact, it pretty much is essential.  Thanks.
EDIT: Found a couple.  PS3 on QJ.net looks good, and PS3Fanboy.com also looks interesting (and not very fanboyish ).  Any others?

See if this helps:

I'm not sure if this will help with game updates, but this should keep your firmware up-to-date.
