I'm also preparing to do this.

Yes it wil. Some rx premap will help.

I will use my home made RX antena for WX-SAT. In fact his calcualted for 
145 noe 137 band. This QHelix. He has excelent gain and is moderated easy 
to build. But this is not low profile type of anntena. Turnstyle antena 
have some deep fades in elevation plane if remmember corectly.

It will dot his job well. But i suggest You to think about replacing dos 
with linux. You will have new posiblites like remote shell (ssh), good 
packet filer and more. Recently i instaled some - about 20 pice. of advantech
boards who hase MediaGX 233MHz cpu with 32 MB ram as routers.
If You have problems instaling it, give me some info. I will help You.

If BP-2 is TNC-2 clone it will be working. Baycom like modems need more 
cpu power but i think it will work under some versions of jnos or linux.
