What year is your CR-V? I'm not sure when they switched the recommendation from 5W30 to 5W20, but I'd stick with the weight they recommend. My '03 has had Redline 5W20 since about 20k; now at 87k we've had no issues whatsoever, no burning, no consumption. I've never had to top it off between oil changes since starting with Redline. It's perfectly clean, too.
I use Purolator P1 14610 oil filters, and no issues there. Used a Wix once, and no issues there either. It's awkward to reach and get a good grip to unscrew unless you put the front end up on jack stands and reach over the left wheel.
I use Honda air filters, as their construction seems far more substantial than any others on the market, including Wix.
I hear so many conflicting bits of advice regarding transmission fluid that I've decided just to use the Honda fluid on the seemingly safe assumption that it is the least likely to do any harm. Others may be perfectly fine, but I don't know -- and that is the point. It's 7.31/quart at my dealer, and to totally flush it I need 9 quarts. It dumps 3 at a time, and in between each 3 I cycle it through all the gears and drive it around the block. Seems like an awful waste of fluid, but that's the way the owner's manual, the Haynes book, and the dealer all say to do it. Be sure to use a new crush washer after the final 3 qt. dump. And if you're going to be towing, I'd definitely flush all the old stuff out.
Changing the power steering fluid is similar. They also say only to use the Honda Genuine fluid for that. The reservoir holds 1/2 pint. I pump it out and refill it 6 times, driving around a little between each time, using a total of 3 pint bottles at a total cost of $12 and change. The whole process takes 15-20 minutes.
There's my 2 cents. Enjoy your ride.
