The different Keyboard Layouts are only required if your particular VNC server doesn't support "Direct". In practice, the only server that actually seem to require them is the one included in Mac OS X. For most other servers, either in Windows, or Linux, you should use "Direct".
About speed, Remoter is one of the fastest VNC clients on the iOS platform; but certain specific things can cause serious slow-downs. The main culprit seems to be resolution: If your computer screen resolution is high (higher than 1024x768), a lot of memory is required, and iOS devices are seriously limited in this aspect. Another setting that can affect performance a lot is the color depth. Make sure you are using 16BPP, not 32BPP. You can also tweak other settings, like JPEG compression and quality settings.
