First welcome, we love new players!
Second, if you see a 'spirit steed,' run the other direction.
As for your questions:
1) once a stat is maxed it's maxed. Should you lose a level do to fleeing or energy drain or curses from imms, a random att point will return if the last level gained a stat point, which may make a stat that was just maxed go down one.
2) Con doesn't affect life length, but it is CRUCIAL to a necro. Your hp determines the hp of your animated undead, so if your con sucks, your wraiths (when you get them) will die to NPCs. You really ought to max your con as well as your hp trains--you can train hp, pe, and mana just like stats. If you already have two maxed and your con is unhealthy, it may be more prudent to max hp next, then put some into con before starting art. You wont have many points (6 hp is your max and 14 art = 20 trains, which you may not have) so you may need to max con using items. Cha is used for ordering as well as xp bonus when fighting NPCs so I hope it is already naturally high, if not you may need to look into items because I strongly recommend hp first, then some con, then a messload of art (10 should be fine).
3) Animate life grows with level I guess, since my wraiths seem to last a longass time.
4) There are no other benefits to languages.
As for my tips, from one necro to a new necro:
1) If you see any of the following run immediately until you are more confident in your sk skills; spirit steed, elves, griffons, anyone wearing symbols of nature or lots of 'woodsy' or 'wilderness' looking crap.
2) Don't worry too much about the stat stuff, worry more about your character as a whole. You will most likely not become a pk machine with your first char, but hey, you never know.
3) Use proper punctuation and capitalization when speaking in the mud... I know it sounds dumb but you can be taken as either childish or any number of other things you don't want to be considered. It takes a bit more time and focus but it is worth it: remember, mud's are text based so you are judged by your text.
4) If you have questions feel free to use the mentor command from your home country's inn/training area. Also use the titles in the who list to find people that may be able to answer questions and such. For example.

[--- ---] Raena Mynavayr, Priestess of the Eye
[--- ---] Ilphyrean - Priest of the Great Cycle
These two are obviously priests which you will need to know at some point(when arsilan kills you). Type 'help immortals' and 'help <immortal name>' to learn more about what religions and priests would aid you willingly and who you would have to lie to. In this case, the Eye is the dark side of Ain, who would probably help you, while the Cycle is Nashira, mother nature, who--if they knew you were a 'defiler of nature'--would skewer you.

PAR Sha] Golg 'oroth - Wrath of the Serpent
[--- ---] Korv - Voice Of The Wild Spirits, Mentor Of Spirits
Anything with 'Speaker,' 'serpent,' 'spirits,' etc is most likely a shaman who can help you gain life if there are no dark priests (or light ones that you havent already tricked into a res) around.
That about does it, good luck and thanks for joining us!
ps, you can never leave.
