Are the sentences correct and what is the difference in their meanings?
All three sentences are correct. Ignore TCR's comment about the use of "facing trouble," which is acceptable, and a commonly used idiom in English.
The first two sentences differ only in that sentence two is more elaborate than sentence one, but still says the same thing. To that extent, sentence one might be preferable to sentence two.
As already noted, sentence three involves a hypothetical case, and therefore uses the present subjunctive and the present conditional--and you were correct that "were" is the correct verb form to use.
