I would just bed and shoot; the action will break in and if it isn't sufficiently smooth after a few thousand cycles then it would be worth sending it out to be "slicked up."
Make up some dummy rounds and work them through the action, I found my CZ 550 458 win mag's feeding problem that way, a little work on the rails and a new follower spring solved the problem.

I am no fan of the "set trigger" function -- the first thing I would do would be to either back out the screw until it goes away or remove the mechanism altogether (instructions on CZ-USA website).
Other than the bedding you've already mentioned, I would also check the magazine spring strength. I've read several reports about weakness in the stock spring leading to feeding issues -- easy to replace.
the rest of it is kind of "personal preference" stuff -- monkeying with the sights, barrel length, stock shape, etc.

I have a 602 off for a new bbl. It's going to be 21", no more. I handled a CZ550 with a 20" bbl and was sold. The difference in handling for those rifles is like night and day.
Having said that ... If I had a 550, I'd get it cut to 21", get it bedded, add a good pad, get the stock done in a dark oil finish and clean up the checkering. Maybe add a bbl band swivel thingy.

I've had my CZ550 375 H&H for about 5 months now and I like it a lot. I've had some significant work done on it, but almost everything was personal preference (it wasn't needed,but wanted). Get it glass bedded, maybe have dual crossbolts put in as well. I think the trigger is actually fine, the safety works like a Rem 700, so if it's what you're used to it's also fine (forward is fire, back is safe). Make sure your iron sights are regulated before you scope it. Other than that, enjoy it.

MUSTS:
1. Action steel bedded
2. Action polished & stoned
3. Set trigger removed
Nice to have:
Stiffer spring
bolt jeweled (helps smoother action)
shorten barrel to 24"
replace rear sight
barrel band

I forgot to mention the trigger work. I like set triggers on some hunting rifles, mainly Mannlicher style, but not on a DGR. I assume you meant- shortened barrel to 21". I know a number of CZ owners have gone this route but I find the weight & balance OK. But then I am 6'!" & 245pds. I am sure the rifle balance would be improved by shortening. Good hunting.

Nope, I like & recommend 24" on a 375, especially a guy like you who's tall. That's what Model 70 Safari Express' have and it's a perfectly balanced rifle. jorge

Shoot it before you rebed; my 9.3X62 shot fine just the way it came. The set trigger function is easily disabled; no need to remove it. The action will smooth out by being worked while watching TV or some other mindless activity, or have a gunsmith you trust slick it up.

It's not just to improve accuracy. Quite often bedding will keep the stock from splitting at the tang or recoil lug.

I checked out a friend's 20" CZ and was sold. The improvement over the 25" made it a totally different gun.
I liked so much I had my Rem700 in 375/338 cut to 21" and ordered a 21" bbl for my 602.

My CZ 416 Rigby came from the factory with dual crossbolts and both recoil lugs steel bedded.
I don't find the set trigger an issue because it is engineered so if you adjust the pull weight down, the set feature is disabled (I think JB wrote about this happening in one of his articles). At any rate my trigger breaks at a crisp 3.5lbs with no set issues.
My rifle out of the box was the roughest bolt gun I have ever worked on. After a lot of work, today it is smooth as glass and I am really pleased with it.

My .375 CZ American Safari was issued with dual bedded recoil lugs and a decent trigger.
The only two things I did were to add Burris rings for my S&B Flashdot and move the front sling swivel QD stud from the bottom of the forend to a barrel band.
Actually, come to think of it now, there was a third thing - I plugged the old front swivel stud stock hole with a walnut dowel.

I just picked up a Safari Classic, 375, and have no problems with the set trigger. Why not adjust it for a decent standard and set pull and have the best of both worlds. YOu do not have to set the trigger to fire the rifle. Mine, unset is so good, really better in my mind than when set, I do not use the set feature.
