Hello my friend:
Here are some initial tips of the game that any character will find useful.
Every day you play, I would go the Horse Stables and pay for a horse upgrade. I suggest bag space first. It takes 60 days to max one of the upgrades. If you will play multiple character, i suggest parking all the characters at the stables so they can be upgraded each day you log in.
Once you hit level 15, you will be able to weapon swap. I suggest putting all the skills you want to learn but may not use at the moment on the 2nd bar. Prior to turning in your quest, swap to the bar with skills that are still progressing and they will gain experience when you receive the quest exps. Skills gain exps when you do if they are currently active on the bar. So if you are weapon bar 1 and kill a mob, all the skills on weapon bar 1 will gain exps. I also will always put one skill on the fighting bar to level up, that way it does not take forever to level skills.
There are bag merchants in the main towns. You may wish to buy those bag upgrades (10 per purchase). With bag upgrades and horse bag upgrades, you can have 200 slots of inventory.
No matter which character you play, its best to learn as many skills as possible. You never know which skills you end up using at a later date. Which are better morphs, you will need to research or ask since some are better for PvP or PvE. Or some are better in certain play styles. Some players have both morph of skills learned so they can change to either when necessary but you do not need to do that.
I would put the dodge roll on the middle mouse button (scroll button) - Malice Synn tip.
I would learn to block, dodge roll and interrupt/bash attackers. This will help you in the harder content later on.
Heavy attacks help you regain stamina or magicka depending on your weapon you use. It will be an important skill to weave in your combat.
If you wish to craft, I would "research" items on a daily basis, when you can. To learn all the crafting armor types will take a while. Best to do so consistently.
There is mods that will make your game life better. Those suggestions you can ask directly in discord.
Those are my tips for now.
