Photo Coversion for Indesign ?

Question

I am a photographer using LR and photoshop and wanting to know the best workflow when preparing photos for a Indesign brouchure - I am using a new  external designer to produce these but use my own printer so have been able to correct some of the minor colour issues. I know Indesign allows use of both CMKY and RGB - designer is requesting me to convert Photos to CMYK JPEG which i can do but in the past never done it this way - have always provided resized PSD file and final conversion done by designer. Are there issues doing it this way or is this ok.

John , thanks for comments and communication i have thick skin so not easily offended and its always difficult to communciate everything in this manner. For your info I have a Epson 4900 ( no rip considering buying ) I print using Epson paper only usually luster , semi gloss some tradional all using correct epson driver , I use some other brand canvas and testured papaer but not often. I have a good workflow , everything calibrated and use lightroom for printing primarily- I know you dont use it but it has a great print module and providing you use the correct colpur profiles , paper , ink etc has a excellent result with the ability to add sharpening , brightness and sharpening at the end . I am pretty much able to get a greast result first print. All my files are raw 16bit so exporting to Photoshop as AdobeRGB or whatever is easy so far your suggestion of using AdobeRGB rather tahn PROphoto is proving to be better option.
I understand now the print proof process and know i can use external source for this but also believe given above i can get a reasonable proof from my system using above and the 300gsm tradional paper which is similar to what external printer is using. I printed a DL flyer over weekend last and it looks great so realworld test. I now have correct  CMYK profile from my printer.
Now my designer has prepared in indesign a new DL flyer in fact there are 6 ( printing option ) of them all slightly different ( they are gift promotional vouchures or similar?   A couple have identical backs and all have 4 photos on  front  around 3.5 x 1.75 inches some more some less. I might add the photos are complexe and resizing bleed etc all critical . It is at this point after some colour errors in a previous job my designer says , hey I want CMYK files as jpegs please . Not knowing  the Indesign process this is where i started out communciating in my first post. Now i know she is using the wrong CMYK profile ( she told me swop 2 always works ok for her ) and isnt open to learning like me
and i think she feels i am too fussy. I had hoped to resize photos give to her and get artwork and wanted to communciate all i have learned .I think she has no ownership in job just wants to make sure she is not responcible for any errors.
I figure now its easy for me to get the Indesign file from her what is the file type i need to get ? is it a EPS  LAYERED  ? and do my self or have someelse do under my instruction. In any case this job has been on hold for a week so need to action something.
One final thing - should i consider learning indesign myself - I dont do a lot of printing other than photos and photo books which are all done via Lightroom ) it has a book module ) so never felf it was worth while investing time in this - which i have less of ?
