Going back to the original post, I have thought about it and decided that there HAS to be another room in the house they just haven't used as a bedroom. Maybe some sort of sewing/storage room, with boxes floor to ceiling with the sewing machine on a table next to a wall? I dunno--anyways, there should really be some sort of way to find another room for Clark besides the couch.
As for the whole Clark/Lois thing, when it comes to L&C, Clark/Lois all the way, but Smallville Clois makes me shudder. Lois on Smallville feels like a separate character that just happens to share her name with another person. Whereas Chloe has always felt like the sort of person that should be Lois. If it weren't for the choice to bring Lois in for S4, I would have LOVED Chlois--where Chloe becomes Lois somehow. The end of season 3 would have been a perfect place (wish more fics had been written to make it so). Either way, I still feel there's more potential for Chloe to become the Lois from L&C than for SV's Lois, who just annoys me (and L&C's Lois is endearing to me even when she's rude/mean, still gotta love her). I don't know how people over here feel about it--there's a large contingent of people on K-Site who support it, and an even bigger group that just plain LOVES Chloe, me included. She's what I watch SV for, really, though Clark is definitely a major factor. And I really hope they have lots more Chloe on-screen, because the COST is getting very low. (COST = Chloe On-Screen Time, if you don't frequent K-Site's Chloe threads)
