he'll get more regular and predictable. Everything will- eating, sleeping, activity levels, moods, digestion... though young babies are just changing so fast that just when you get used to something being normal they tend to have some major leap.
I started EC with my daughter at 2 1/2 months and it was very laid back and part time for a long time. we did diaper free at home until she started crawling (just before 6m). then we did coverless diapers, modified trainers, a lot of the time.
Personally I would do only as much EC as makes you comfortable and not stressed out right now. 6 weeks is so young. You can use a loosely fastened cloth diaper, or let baby lie/sit on a couple of prefolds so that misses aren't a big deal (or maybe misses aren't a big deal to you, I don't know. we had carpets and I was happy to keep them relatively clean.)
You can try a set schedule of potty opportunities (every hour, every 2 hours, etc) or, always try at a certain time (upon awakening, 5 minutes after nursing, whenever baby seems fussy... whatever works for you). You could try a day or two of observing baby if that works for you (it was always an overwhelming idea to me). I think even if there is one time of day you can usually make a catch, go for it, and even if baby is in diapers the rest of the time for now, you are laying a foundation of what the potty is for.
You can always continue to communicate about elimination even if its happening in diapers.
For out-and-about, we used diapers until DD was very reliably dry. This happened around 14 or 15m or so. I still bring 2 extra sets of trainers and pants (she's 18m), and there was a day where that wasn't enough! ARgh. Again, people do what works for them but I found I didn't want to be stressed out about a miss, and that my baby didn't really like using unfamiliar potties or going in the car, so, diapers it was. I still offered potty chances whenever it was convenient, and frequently she would have only one or no wet diapers, but her elimination didn't structure my time or dominate my thoughts, and that was important to me.
