Thankyou everybody for nice response, suggestions and lessons Really appreciate it

The problem of the band is that all of the equipment they got is borrowed or hired. So all of it will go away quite soon. The next big gig is after a month, so we need all kit at once straight away ASAP. We got money, but we don't have time and this is the biggest problem. If we purchase all kit now, I will be able to get familiar with it during one month (two people are working as a sound lads for a band) and band is rehearsing lots of time.

So I updated the list of needed equipment and took in account all the feedback. Can you please take a look again and answer my questions if possible.

(We got all needed cabling, two DI boxes, guitar amp and micing for it)

Stuff I plan to purchase.
(Mixer)
Behringer X32

(Amps)
Crown XTi2000 Series (Set of three amps)

(MiCs)
Shure SM58 (x2)
Shure DMK57-52 (For drum kit)

(Speakers, Mains)
JBL MRX515 (x2)

(Stage monitors)
JBL MRX512M (x4)

(Subwoofer)
JBL MRX518S (x2)


BAND - mainly performing Rock, no keys, no additional instruments.
1. Vocalist + Accoustic Guitarist
2. Back Vocalist + Lead Guitarist
3. Bass Guitarist
4. Drummer

So,
What do you think about the kit? Is something really wrong? Or maybe something good about it?
And usually we do Bass guitar DI'd straight into mixer. Is that wrong? (sounded quite nice with pretty crap mixing desk and crap speakers)
Can you suggest me some industry-standard overhead mics, please? I have a lot of them in mind, just afraid to get it wrong.
