Stop sitting around getting satellite locks and try using the GPS on the road
Going into the secret GPS settings and messing with the SUPL settings etc were first reported to help a long time ago after the phones came out but never really helped at all to be honest. In fact Samsung came out with an app to put these settings back to the default after people messed with them and found it didn't help. I tried changing it to google and it seemed to help for a few days but it went back to the same old crappy performance. The only thing that helped with the locks was the official fixed rom that came out a while back. The locking is still a little slow but it locks on a lot more sats when it does lock now. My issue is with the tracking when actually using the damn thing on the road.
The unofficial Froyo roms may make the GPs perform better though.
Man, you should look into rooting and running some of the custom roms if your having performance that's that bad. I couldn't get lock for crap on the first two official roms for mine but it's been excellent since. I've been using all voice commands lately and it has been deadly accurate so far both in recognizing the commands properly and in navigation. the only problems I've notice are in the instance when I'm on a highway or major road and another road runs parallel within 100ft or so, sometimes Nav gets jacked and places me on the wrong road. My understanding is that has more to do with Google's beta nav software than it does with the hardware. AT&T Nav, TomTom, etc. all reportedly provide more accurate results but I'm too cheap to try any of them and Google has been getting me exactly where I want to go.
If it makes any difference, GPS has been great for me on 2.2 and 2.2.1. I've fooled around with 2.3 a couple times but haven't tried a build yet with working GPS though they're floating around now. GPS was not good for me on 2.1 for whatever reason.
