Help with export from LR

Looks fine for the most part.

For Print : Setting the resolution to 300dpi will resize the photo to whatever size it will be. If your image (for example) is 6000x4000, this will result in a 20x13 "sized" jpeg. If you try to print on paper that's smaller or larger than this, then the lab will be resizing it for you (either up or down). 9/10 times this is fine with modern cameras having quite big sensors and going down in size is usually much better than going up. But if you're trying to print a 20x13 from a tiny image file (smartphone for example) you're relying on the lab to upscale for you. If you're fine art printing a single image, I'd use the Print module to output a jpeg that's specific to the paper size. If you're printing lots, then this would probably be ok.

For web - looks fine. Remember that resolution is irrelevant when you specify pixel size, so don't worry about it.

Finally - I've not had much success with Output Sharpening - either for print or web. I find it sharpens everything. My advice would be to test your exports with it on and then off to see if you think it improves things. Depends whether you sharpen much in the Develop module really.
 
For web use there is no need to export @ 100%, it just makes for a bigger file. I've gone as low as 65% but certainly, 75% will give excellent results. I have some test images on my flickr demonstrating this if you need me to link them, let me know. Agree with Ian re the print module, it offers you more control. Worth speaking to the lab about their profiles too.

Thank you for the detailed reply
In rgeards to the print version, its not for me and the client will print photos themselves and i dont know where they are going to do that.

Thanks, if i download web version on my phone, photos look ok, but if i try to enlarge, then i can see pixels and generally not clear, is that how it should be?
The print version is for client and i dont know if and where they are going to print them, i just wanted to give them 2 versions for web and print as an option

Not really sure tbh as I'm not sure how your phone will download the images. In general, if an image is enlarged (by zooming) then it will start to show pixelation no matter at what quality it was saved.

If the client wants to print the image, then exporting it at max size and at high quality with sRGB profile is the way to go imo/e.

Its probably the case with zooming and pixelation, the image looks fine in LR if I open it on my phone, but its different.
So it should be fine what I did in regards to print size image that I;ve shown above?

The print module is really powerful. Great for adding borders, controlling the print exactly how you want it on the paper size etc. Don't forget you can output to a file, not just print this way.
 
For physical printing I tend to output to the size required at 300dpi, so if I'm printing at 12 X 8 * 300dpi (3600 X 2400) etc. I set both resolution and print size. Obviously that results in a much larger file if going 20 X 30, but a small one for 10 X 8. I also usually output as TIFF (mostly because the printer I used wants files that way for larger images) and set sharpening to low.

As for compression for jpg files, this is a curiuous matter. I've had some files that have developed strange banding and artifacts when output at a sensible compression (say 80 or 85) but find it can be hard to reproduce that effect reliably when trying to prove the point. However you can see an example in this thread: https://www.talkphotography.co.uk/threads/lower-heyford-narrowboats-one-shot-multiple-images.650485/ third image down, the 'texture' in the sky should consist of subtle shades instead of the splodges of magenta and blue-cyan that are visible. These were output at 85 IIRC. For printing I cannot think of a reason not to use 100 IF you want to use jpg output.
