There aren't really enough comfortable and well located quests in the game to reach 60 with purely questing. For this reason I wouldn't recommend grouping up for every quest. However there are group quests in basicly every zone that often do require groups.
Instances are a good way to gear up a bit, but if we're speaking strictly experience then it's often not worth doing them more than once. This first time being to complete all the quests in said instance.
That being said, if you have people that you enjoy playing with, why not group with them anyway. It might be a little slower but it might be more fun for you. Personally however, I prefer to just sit on teamspeak with guildies or chat with them in guild chat while playing, because I feel constantly being grouped is too detrimental to my leveling process.
Regarding professions, I would recommend trying to keep your professions up to date, possibly excluding fishing. For the other professions (except maybe cooking) you should get enough recourses while questing/grinding/travelling anyway so that you do not have to spend a large amount of extra time searching for nodes or mobs.
