I reckon you'll be good to go to bottling. 4 weeks in primary should have let the yeast do a nice bit of cleaning up and mellowing/melding of flavours. Three weeks warm conditioning and then chuck a couple in the fridge for a few days and you'll be enjoying a nice drop, I'd wager
You'll probably gain a couple of points increase in ABV from priming but not all that much. I.E an increase from 6% to 6.2%, maybe slightly more.
