(Realise there's a 'where should I start thread' but I've got a tonne of questions and thought they'd stand a better chance of being answered in a separate thread.)

So, haven't read any comics in years, and even then all I've read are some books/major events like Civil War, Dark Avengers, World War Hulk: X-Men, Messiah Complex, House of M so I have a slight idea of events/timelines.
 
Been wanting to get into it properly for a while though and read something ongoing. Just finished reading the Apocalypse Situation and really enjoyed it so I'm thinking of going with Uncanny X-Force but I'm a bit worried it'll end up like the last series I was interested in (Dark Avengers) and end pretty quickly. Impossible to say I imagine but do people think it'll be something that goes on for a while? I'd also like to read some X-Men but no idea which series to choose, X-Men/Astonishing/Uncanny/whatever else there is. I guess I'd prefer the series parallel to Uncanny X-Force unless there's another that's significantly better.
 
So basically
 
Uncanny X-Force, finishing soon or  long lasting ongoing series?
How many X-Men series are there?
Which would you recommend I read alongside X-Force?
Any necessary back reading?

Think that's all for now, thanks a lot in advance.

YES ANSWER THESE QUESTIONS lol sorry i have exactly the same ones im just too busy to get back to comics and waiting for the trades

Now I'm a few months behind, but I'll do my best:
 
1. Uncanny X-Force should be long running. 
2. Aside from the titles featuring solo characters (X-23, Daken, etc.), you have these:
 

• Uncanny X-Men
• X-Men Legacy
• Uncanny X-Force
• New Mutants
• X-Men

• New X-Men (Grant Morrison run)
• House of M
• Deadly Genesis
• Rise and Fall of the Shi'Ar Empire
• Endangered Species
• Messiah CompleX
• Messiah War
• Second Coming

The good thing is that Uncanny X-Force is, for the most part, self-contained.  The same can be said for X-Factor; both are two of the books in the new "Wolverine Team" lineup (don't ask). 
 
If you like Uncanny X-Force, I suggest picking up the previous X-Force book, as well as the whole Necrosia storyline (which is X-Force heavy). 
 
Suggested X-men reading as of now: 
1.  X-Factor - a solid, stand-alone X-book.  Very little "when did this happen?" going on. 
2.  Uncanny X-men (the current Fear Itself tie-in is good.  It's resetting soon, so I don't know about future) 
3.  X-23, Daken, Wolverine ("goes to hell" was the first arc of this onging book). 
4.  New Mutants - generally solid NM X book.
 
Generally avoid: 
Wolverine:  The Best there is

  both are two of the books in the new "Wolverine Team" lineup (don't ask).

@JediXMan: after the current event Schism...the X-men will be split in two...some will be going to Westchester with Wolverine and appearing in the new title Wolverine and the X-men...the others will be staying with Cyclops on Utopia in the renumbered Uncanny X-men...it also appears that the other teams will pick a side as well...including X-Factor, X-Force, the X-men title, X-men Legacy, and Generation Hope

I guess I should read schism then? And does this mean X-men, Uncanny X-Force, Legcacy etc are ending? Or does Xforce just carry on without Wolverine? And renumbered as in 1? 
 
And could you be a bit more specific with the previous xforce book/necrosia/xfactor stuff, thanks for all the help.

@JediXMan: Thanks dude, very helpful. What about the Bastion getting rebuilt/choir and Selene stuff? Not important or is that a part of the stuff you mentioned? Oh and am I right in thinking Legacy/uncanny xforce/uncanny xmen are all the same universe, just different teams? Thanks again

the only title that's ending is Uncanny and it's not really ending just starting over with a new number 1  there was an X-force volume before Uncanny X-Force that if you're going to read everything then it's kind of important...though I would just start with Schism

@JediXMan: Thanks dude, very helpful. What about the Bastion getting rebuilt/choir and Selene stuff? Not important or is that a part of the stuff you mentioned? Oh and am I right in thinking Legacy/uncanny xforce/uncanny xmen are all the same universe, just different teams? Thanks again

I don't think any of the series is ending and you don't necessarily need any complimentary series to read alongside X-force. I've dropped both X-men and Uncanny X-men for the time being but will probably check them post-Schism. For a second X-men series, you should just decide what X-men you would want to read about and go from there.
