Wow! I thought my replies were long! 
Sorry, I'm so used to working on compaq/hp laptops I forgot this could be a desktop.
The only real difference IME, is that desktops tend to have more standard well known components that you are likely to find drivers for, though this can't be assumed.
Putting "Presario SR1000" into google.co.uk gives us the HP support website at the top of the hits, but you see a lot of different models. Then searching in this page on "SR1460UK" gives another long list with SR1460UK in it, choosing this gives us:

Here we see the driver downloads and see that there are only XP drivers from HP for this machine. Don't take this as anything other than HP not bothering with this model, doesn't mean yes or no for W7.
The spec of your machine looks good to me for going with W7, and the report you post is promising as far as I can see.
Most of the failures are not an issue, either because there are not needed for W7, or have suitable free replacements. The modem looks dodgy (if you need the modem), so if it's essential, you must check further, but it could well still just find a suitable driver from MS once you are internet connected, or even work with a generic driver.
I've found generally the main gotcha's are graphics card (ok here), sound card (ok here) and network interface if you use it (ok here). Otherwise, often the next to watch are the m/board components, but you look to be ok.
You must check your printer's website for W7 drivers and software, although even if there are none, there's a good change it will still have MS drivers available (but more of a 'try it and see' senario then - so a small risk), also googling any unknowns for W7 will maybe get you feedback on others having done same. In fact you may even find others who have converted your model PC to W7, so google is your friend here.
You could really benefit from another Gig RAM, but this is easy to fit and fairly cheap (25-30 ukp, maybe even cheaper). Just make sure it matches.
You must have something to backup data to (should do this anyway, don't trust one hard disk with your irreplaceable photos or whatever).
Personally, with your PC, I'd go for it, but then I know I'm better off with 7 (and quite like it), if XP's done you proud and has no problems, then is it worth it?
I believe there is still a 90 day demo you can download from MS if you don't want to risk paying first before you know it works, but have your data backed up, and an XP install disk so you can recover if it all goes wrong!
I'm not the worlds greatest expert, but I often get pretty close to right *most* of the time. I think you've a very good chance, but you need to allow for the possibility of problems, don't take this as a guarantee!
You don't have a modern whizzy PC, but from your stated use, I think that you'd be fine with the extra 1G RAM. Some people may feel I'm leading you up the path expecting to use Win7 on this machine, but I feel that often PC's and laptops are overspecced for what the user really needs. Don't expect to get another 3/4 years satisfactory use though (though you never know), you need to bear in mind that often an OS upgrade can also tempt application upgrades (like going from Office 2003 to Office 2010, for example), and you may start to see slowdowns with this sort of thing.
- Always be prepared to go back to your old OS (data backup, XP install disk, critical drivers (esp. network card so you can download more drivers) etc.), and you can only lose time (and learn a lot more about your PC too!).
