Recently I ordered and installed the memory upgrade for my PA-500. It was under $400, is a simple end user install and upgraded the management plane to 2gb (from 1gb).
I will not give any estimates as to improvement as I do not want to exaggerate, however, I highly recommend anyone with a PA-500 spend the $400 (ish).
Hope that helps,
Let me just say the difference in the console is noticeable.
Unfortunately I did not take a system resource before. Maybe you could post your stats for a comparison?
I am using 5.0.3. After the upgrade "show system resources" is as follows.

PA 500 with around 100 users behind it

As I can see from your output, in your device, the swap area is not used.
Do you see any difference when you commit (time, etc) ?
Unfortunately I did not do any pretesting. Even if I did it would not have been valid as I took it to 5.0.3 at the same time.
It is my opinion that everything is quicker including the commit process. Fro $400 (ish) I would suggest you give it a shot. Best money I have spent in a while!
Normally, from CLI, when you commit you see dots that show you the progress.
Here are the times.
Based on these times, I would say that there is faster commit times, we saved closed to 25% of the commit time (~30 secs)
Student5 Swap: 2212876k total, 303200k used, 1909676k free, 129612k cached
Student10 Swap: 2008084k total, 0k used, 2008084k free, 1143148k cached
Then, from CLI mode, I loaded a script, which essentially loads a configuration and does the commit automatically.
Here are the times.
We are consistently seeing an increase of load capability and commit response times of 25%.
