Regarding the soldering of the headtube, is perfectly fine. I got the frame from London Bike Kitchen and they said it was safe, then I found the original owner sold it here on the forum stating he had it fixed and rode it for two years with no issues.
Check his original thread:
I also sent pictures to AlAn and got a response from "Al" himself stating the cracks on those lugs are perfectly safe as there's more to hold the frame anyway.
The response, in Italian, is here:
"Buongiorno,
purtroppo non c'è più alcuna possibilità di effettuare delle riparazioni su questi vecchi telai Alan.
Dalla foto la crepa è molto profonda ma, considerando che con la congiunzione superiore, il tubo sterzo e il cannotto forcella fanno tenuta , serrati dalla serie sterzo, per noi non dovrebbero esserci problemi di improvvisi cedimenti del telaio.
Ovviamente non possiamo garantire questo al 100% considerando l'età dei materiali.
I paid £50 for it, so I'll pass that onto you (might go down as little as £40).
Finding the exact forks won't be easy, but if you are not picky as I am there'll be hopefully plenty of cyclocross forks around.

I am trying to build it up as it a shame to have it hanging and will do if prefer, understandably, to go for something else:
