AFAICT it always seems to be 練習問題. Probably best not to add it.

would 'exercise' be a good fit for sense 1? or is that always 練習問題?

"火蒜" gets 16 results on bing (when restricting it to 
Japanese results). Most are false hits (i.e. "（火）蒜" etc.) 
but one mentions what seems to be a Chinese delicatessen, 
"金山火蒜". It seems the characters can be used to mean 
"roasted garlic" in Chinese:

http://baike.baidu.com/view/1076881.htm
The "火" in place of a "大" in Kenkyusha might be a typo? 
Hard to tell.

See below.

I have now got my Google counter working and I can see that "big" gets the big hits and "fire" does not. I wonder why Kenkyusha gives "fire" [checked again with magnifying glass!!]

See below.

In Kenkyusha, it shows the kanji as "火蒜" alonside "ニンニク" for garlic. "Fire" as opposed to "big" has some logic!!

Google hits seem to show "火蒜", with a fair number of hits.

After making an amendment above changing "大蒜" to "火蒜", there was a "caution" note about cross-referencing so I have restored the original entry and I shall leave it to you to make the amendment; just in case I end up losing the cross-reference link.

GG5, etc.

Usual format. Came across ニンニク (ニンニク絞り器).

I'm not convinced about じゃむ either. Never seen or heard it.
The "clash" sense isn't a noun. Changing it to adv-to.
I think the reading restriction is correct and we should swap the order of the senses.

No response for a week. Closing.

Splitting off the じゃじゃーん versions, and adding in Nicolas' proposed じゃん & じゃむ. I'm not convinced about じゃむ.
Also should sense 1 be restricted like that? Is the sense order appropriate?

"jaan" and "jajan" should probably be two different entries. And Nicolas じゃん suggestion should maybe be merged into the "jaan"

My opinion is that all [exp,(verb)] entries should be the in infinitive form to the extent it's possible, but I'm happy to gloss it as 
an adjective if the usage warrants putting an adj-f first, which I'd say is the case here. Actually it seems to hardly even conjugate 
at all so it's probably fine to even remove the v5k.

I liked it the way it was.
I don't think all the ...が... and ...を... expression need to be translated as infinitive verbs. In this case 今をときめ seems to be mostly used pre-nominally:
GG5: 今を時めく大スター a mega-star whose name is on everyone's lips
GG5: 今を時めく人気歌手 a singer at the peak of her popularity
中辞典: 彼は今を時めく歌手だ. He is one of the most popular singers today.
Perhaps adj-f here?
