there are server path or folder informatins saved in DB?
To transfer the DB, do an Export in PhpMyAdmin of the local DB and an Import on the remote. Make sure the charsets/collations are the same for both DBs.
No. It’s in config.[core/inc].php files.
Just copy the files + db to your remove server. manually fix these 4 files, or just run the modx setup again (it’ll fix your config).
