Still not sure how to distinguish the use of these two.  Any help?

I met this sentence: Tu y vas samedi? - J'y vais tous les samedis.

Could it also be: J'y vais le samedi? 

Merci d'avance

"The weather was wonderful."  There is no clear beginning and the end, so why is it in passé composé?  Can I say "Il fesait beau."?

I think this is a typo in the last sentence.  It should be "cet après-midi" not "cette". 

Are there verbs that don't follow the structured outline noted here - 'stem' from future simple conjugation, 'endings' from past imperfect conjugation? I think that I have not yet (early days) come across a verb that does not conjugate in the conditional in accordance with these simple 'rules' and having this clarified could/should/would make it much easier to remember. Even for irregular verbs it seems to me that if you know the imparfait and the future simple (both of which are also pretty consistent with 'endings' but not the stems) you have all you need to know the conditional.
