Few quick tips that should help since you are a group who plan to play together alot:
-For crafting, level crafts that will compliment eachother. Have one person work on fishing+woodworking,(100 fishing, 60 woodworking and work towards lu shang's), one person on cooking and alchemy, (100 cooking, 60 alchemy) and then the last two on a high priced craft like goldsmithing. the last person can pick something for fun or take THF to 75 and help everyone farm ingredients. A straight source of farming materials to craft will keep everyone's synth costs low and profit margins that much higher. It's easier when you're all friends and know you can trust to get materials for free or discounts from your friends.
However if you plan to go hardcore into end-game you might want to consider having someone do bonecrafting/leathercrafting/clothcrafting because some of the drops from end-game mobs are a great way to make profit if you keep the materials and synth them.
-Warrior can tank but I'd suggest having the war or mnk switch to ninja or paladin. Or have the war switch to samurai (I mean, as far as first job to 75 is concerned. what you have now is a good setup)Because once you get higher in levels, if you want to exp in a full group of 6 you might be hard-pressed to find a good tank, so its best to have one ready to go each time. RDM+WHM is a great combo and the only way to improve it is to make it RDM+BRD, but only for exp/merit parties at 75. For 4 people to do everything in game, i suggest having everyone level 2-3 jobs to 75 with the following groups doable:
sch(or 3rd blm)
//tank party for HNM/survivability
blu(or thf, if thf, rdm needs drk sub for stun)
\\merit party(exp parties at and beyond 75 are called merit parties)
You can basically attack any aspect of final fantasy with one of the above job groupings of 4, without seeking outside help. Not mentioned above is RNG and the solo job classes. RNG is a great addition because it is like a BLM with ranged damage but they can spike harder damage when needed and generally survive longer. Don't worry about race choices when thinking about jobs, except elvaan/galka BLM and tarutaru tanks are the only things I'd say to avoid.
Personally I don't know any LS that take new players with a thought on the hardcore end of gameplay. Most LS that take new players are filled with new players, and they probably aren't concerned with being hardcore or playing to the best they can possibly play. It'll be tough to find a good LS with alot of members, you're more likely to find an LS with a few vet 75's with a total member count of 5-15 that will fit your same passion for excellence, but fairness(if you guys are into that whole fair and good person thing^^)

If you need a bard to get "good exp" in a merit party, you're the weakest link.
