Very new user hardware recommendation

I have a friend who is a wonderful singer/songwriter that wants to get started with a DAW.  I use the R24 with an ASUS PC with an M1 Audio Axiom 61 keyboard.  I use a pair of NS10's and have several mics. 
Here's what I think his price range would be:
 
ASUS PC & LCD monitor:    $1,000    
Digital interface:                 $300
Keyboard                            $500
KRK 6's speaker                $400
Shure 57                           $100
Plugins (Piano, DimPro, Studio strings)  $200
Sonar Producer X1E          $400
This totals $2,900
 
What would you recommend? 
 
Thanks to all who contribute!  Let's get an very talented guy into the DAW world!

Sonar Pro comes w/ true pianos, Dimpro and studio instruments, I believe, for $400.

If he is singing or recording other acoustic instruments other than the electric guitar a different mic might be better.

BUT - the plugins for $200 don't have to be Dimpro - I'd spend that $200 on EZDrummer. 

I also echo the need for a good large diaphram mic for a singer.  it doesn't have to be uber expensive.  something like a Shure SM-27 is right in the middle for $300 or Rode NTIA for $230.  if you want cheaper, go with something like the AT2035 for $150 or the AT2020 for $100 or the MXL V63M for $80.

I'd also consider a good sampler program like Kontakt.  but that increases the budget quite a bit and it really depends on his goals as to whether he needs everything like that or not.

Hi Guys,
Good feedback! (is that an axi moron?)
I bumped up plugins for Studio Strings, Piano, Saturation, etc. 
Definately need another mic but the SM57 is great for almost anything when you are on a budget and just starting.  The condensers are a must have but you have to be careful on getting too much room noise.  So to be very basic without worrying about that, I thought the 57 was a good first mic.
Imagine if you started all over again with a minimal budget but wanted to build on what you start with.  I think your ideas and mine are headed in the right direction. 
Any comments on a basic ASUS PC? 
Thanks again.
