Nova launcher or stock launcher

Question about using a different launcher. If I was to switch to EX Launcher or Nova Launcher, how would I set the lock screen widgets?
 
After trying all of the ics launchers, I found apex launcher to be the most responsive with the least amount of lag, especially when opening the app drawer. I don't regret switching from sense in the least, except for missing the clock widget.

Im using the world weather clock widget. Find the weather to be more accurate than the Sense weather was and has several styles of clock.

I found exactly the opposite. Apex felt sluggish and lagged a lot for me, Nova is smooth and responsive.
I use Beautiful Widgets to replace the clock. It has hundreds of clock and weather skins to choose from, some of which mimic the sense clock pretty well. You can also set up the widget to open up the clock app like the stock widget does.

If you switch to a third party launcher, how do you prevent Sense and the various other processes that attach to it from starting?

You can?t completely stop sense from running, unless you root. I have uninstalled/disabled as many HTC services that I could (Friend Stream, Stocks, and Watch). This has made a lot more memory available.

I use Nova because I like the stock look and it feels extremely fast (especially when scroll speed is set to Faster than light).
