3 emails to check

Hi there, could someone check these two emails and tell me if there is something wrong with them and why. I'm especially concerned with the usage of present perfect vs. past simple. 1. Please let me know if you (have) managed to prepare a complete list of works connected with my interests. I'm running out of time due to the fact that I have to finish my work untill (before) the end of April and I'd like to photocopy some articles (that are) included in box8. Thank you, 2. Thank you for  his e-mail. I've heard that he took a somewhat  controversial stance on various subjects connected with folklore but I know nothing more about it... so hopefully I'll know more once I get in touch with him. 3. Thank you so much for your answers. I'm obliged to you for answering my questions and for spending time on them. I'm sorry about my slow reply, but my computer (actually the system) has crashed. Fortunately I've not lost any data. I've already asked the staff to search for all  papers concerning the topic and anything connected with it. I've also asked them to search for information about black music influences on the genre in genera. If everything goes well, I'll have accessed that material. Hope, everything goes fine... (I hope everything will go well...) Thanks, best wishes, (Thanks. Best wishes.)

I think the colored parts are what seem to be essential in terms of the paragraphes being correct. The non-colored parts are optional in terms of whether they are absolutely needed to be there, I think.

Of course, I welcome any comments on mine.

Hi,

I used that tense form to reflect that fact that it has some pertinence to the present (situation) in some way. Sorry for not being specific.
