Just to keep them all in one place, here are two tweaks that I thought others would want to know:
1. Disable HTC dialer/Tachi. The stock/default Windows Mobile dialer isn't quite as pretty, but it is functional and uses up about 10MB less of RAM. There are also many themes developed for it if you wish.
(Please note, depending on your rom the ## codes many not function with the stock/default dialer. YMMV!)
HKEY_LOCAL_MACHINE\Security\Phone\Skin
Change the value of 'Enabled' from 1 to 0.

2. Solve 'some' of the ring delay issues in the HTC Dialer/Tachi by disabling the 'incoming call annoucement' in Microsoft Voice Command. Go to start/setting personal tab at bottom/voice command/highlight phone/options. uncheck announce incoming call feature.
There is a registry tweak for this (so you won't have to do it manually), but so-far I have been unable to find it. I will update this post once I do.
