Are you just editing? Or are you mixing it as well? Do you know how your dialog is going to be treated in the mix? Is it a Doc, a CSI style show, a dramatic feature?
If you're mixing it as well you can just go through and edit out the big stuff, then keep an ear out for noticeable things when you're mixing and edit them out then. By that point there probably won't be too much left anyway, so you'll be good.
If you're not mixing it, I'd try and mimic whatever the final product is going to be:
If you're doing a modern investigation type drama that's going to be covered in music and crazy sound design, I'd say make a guess that they're going to be compressing the crap out of the lavs and using the boom for a bit of spice. In that case I'd compress as you do it, and probably go a little harder than they would, just to be on the safe side.
Docs too, depending on the style.
Dramas probably won't be crushed too much, so I wouldn't worry about it to the same extent.
The only thing I'd say is be careful with your settings. If you compress too much with a really slow attack you may end up having stuff jump through that sounds like a click or pop, but really isn't. So you'll edit out a bunch of stuff and end up with a really choppy comp track.
