Just use Ryoma more, dude's a beast as long as there aren't too many lances/shurikens around. Silas is usually pretty tanky, you might want to reclass him to great knight for more defense. He can also make use of the guard naginata (+5 def/res). Azura will always be super fragile, but she's definitely worth using. Just make sure she's never in range of any enemies, except maybe a magic user. Part of the problem might be that your only healer is Jakob. Sakura is very useful, though it might be too late now. If you buy encounters to grind off of, the enemies will be about as difficult as the enemies on the original map (I think, haven't done much grinding). If you're having difficulty grinding, just buy cheaper encounters. Remember that in Fire Emblem, you should usually focus your EXP on the dozen or so units you plan on using, rather than spreading it out on everyone. That's all I can think of. Edit: I just realized that I misinterpreted your problem with Silas. If he's having trouble with damage output, try giving him a silver weapon. Managing the debuffs might be tricky, but at least he'll be able to kill someone when he needs to. If you do reclass him to Great Knight, he'll get more strength, though he'll also lose speed and have trouble doubling (in this case, the practice katana/any raider weapons will be helpful).

I didn't use any horse units. Fortunately, grinding was there to save my scrub ass.
