[Q] where do APK's download to from market?

I am trying to install the new Google Voice Search app, but I keep getting "install unsuccessful" on Bifs 1.5 Froyo ROM. I'd like to download the apk from the market, pull it to my computer then try installing from ADB, thats worked in the past.
So does anyone know the temp location that the apk downloads to?

There seems to be some issue with signatures on the APK. A workaround is here.

[Q] Lost market - how do I get it back?

I have no market anymore - help!
I rooted with auto-nooter-2.12.18 and that market was running ok but I downloaded a "new" market app and followed the instructions to replace my old market app. Unfortunately, that didn't work - it installed but wouldn't run. I uninstalled the "new" app.
I have the apk for the market that came with 2.12.18 (I backed it up) but when I try to install it looks like it is going ok and then I get "application not installed". I have tried installing with Apps Installer and I also tried Astro and Root Explorer. I have rebooted in between. Any suggestions?
I have not done "the adb thing" (I am new to Android and haven't tackled that yet). I can't figure out why the market app I had originally won't install again now.
