Try a Brujah for your first character. They are good generalists. Really though, any clan will do but you should save Nosferatu and Malkavian for a later playthrough as they are most unlike the other clans. In the case of the Malkavians, they don't make any sense at all in a first playthrough because they have an entirely unique set of dialogue options for the entire game.

Combat isn't very difficult early on and guns are incredibly shitty until the latter third of the game. For much of the game you will do well by slowly building up your Melee skill. Brawl is fine against human enemies which make up the bulk of your opponents but you don't need to put lots of points into it. Brujah start the game with an additional point which is going to last a long time. It is mostly used to force feed on enemies during combat (low brawl means they shrug off your feed attempts often).

You really only need one social skill, namely persuasion. Intimidation is not used to solve many quests, and while seduction is more commonly used it isn't nearly as useful as persuasion. Save these for future playthroughs. You can still put some points into seduction for fun even though you rely on persuasion, but skip intimidation entirely.

As for stealth, the actual stealth attribute is rather good despite how most guides are ragging on it as unnecessary. It is a passive modifier that makes enemies ridiculously bad at seeing you from more than a few feet away. You don't need it during character creation but you're not wasting points building it up to 4 or 5 early on.

Do also put points into Dodge fairly early on, it really helps with combat in general.

Your clan specific disciplines are all kinda pointless except under very specific circumstances. Don't worry that you're missing out if you're not spending points here. They are all active abilities and as a new player you may not recognise during which fights they are useful. The game is dead easy anyhow, it's not like you need them to stand a chance of beating the game. Some are quite useful when fighting other vampires, such as the Tremere blood shield, but you can still win those fights just with good footwork or with a good gun. Against human enemies (by far the most numerous)... well, you're a vampire, you can kick their ass without showing off clan disciplines anyhow.
