A girl and a guy

Question

The main goal here is to figure out the one-“word” answer to each of the following clues.

Each answer consists of one (or more) names and one (or more) other words hinted at by the clues. There is, of course, a gimmick that links all the answers together. Once you get one right, it should be clear what the gimmick is and make the rest much easier.

1.  Green guy
2.  Girl you get your illicit prescription drugs from
3.  Compete and guy
4.  Girl poem
5.  Break guy out of jail
6.  Web publication about a guy
7.  Girl (plus the first of her last) and basic substance
8.  Fib and guy
9.  Either of two quarters of a bubbly beverage and guy
10. Flaky thin dough and girl
11. Guy and 1982 movie
12. Church noisemaker and girl
13. First letter and guy
14. Greek letter and guy
15. Greek letter and guy
16. Guy and greek letter and extent
17. Guy atop
18. HVAC fixture named after guy
19. One tenth of girl
20. Possible 1980 slogan for a guy
21. Guy and meditative utterance
22. Perfectly round (except the last) girl
23. Guy and charged ocean denizen
24. Fermented honey and guy
25. Girl and seaperson prefix and guy
26. Formerly guy
27. Guy and dream stage
28. Extremely girl
29. Guy and what you make before shopping (with its indefinite article)
30. Tear apart Johann Maier von and guy

If I stopped there, this might be pretty obscure, so here are the second set of clues. Solving each of these will provide you with one of the guy or girl names you can use to answer the clues above. Note that each clue will lead to a name, but the precise form of that name that is used in the above clue might vary (e.g., “Dan” vs. “Danny”). And also the order of these clues does not match the order of the first set...that would be too obvious.

Note that you don't really need to solve the second list to complete the first list, but it may help.

Since there are a lot of clues, partial answers and collaboration are welcome.

FOR A BONUS: Figure out an answer to the post’s title that fits the gimmick.

Good luck!
