Tooltips are easy enough. They are slightly different for MicroMenu buttons, though.

An example tooltip for the Talents button.

-- OnEnter

local TipText = MicroButtonTooltipText(TALENTS_BUTTON, "TOGGLETALENTS")
GameTooltip:SetOwner(self)
GameTooltip_AddNewbieTip(self, TipText, 1.0, 1.0, 1.0, "")
GameTooltip:Show()

-- OnLeave

if GameTooltip:IsShown() then GameTooltip:Hide() end

Note: TipText will get set to something different for each button.

Button codes are:
MicroButtonTooltipText(CHARACTER_BUTTON, "TOGGLECHARACTER0")
MicroButtonTooltipText(SPELLBOOK_ABILITIES_BUTTON, "TOGGLESPELLBOOK")
MicroButtonTooltipText(TALENTS_BUTTON, "TOGGLETALENTS")
MicroButtonTooltipText(ACHIEVEMENT_BUTTON, "TOGGLEACHIEVEMENT")
MicroButtonTooltipText(QUESTLOG_BUTTON, "TOGGLEQUESTLOG")
MicroButtonTooltipText(SOCIAL_BUTTON, "TOGGLESOCIAL")
MicroButtonTooltipText(GUILD, "TOGGLEGUILDTAB")
MicroButtonTooltipText(PLAYER_V_PLAYER, "TOGGLECHARACTER4")
MicroButtonTooltipText(DUNGEONS_BUTTON, "TOGGLELFGPARENT")

For the GM Request / Help button, TipText gets set slightly differently.

TipText = HELP_BUTTON

For finding out the number of friends online, you'd want something like the following:

-- OnLoad

self:RegisterEvent("PLAYER_ENTERING_WORLD")
self:RegisterEvent("FRIENDLIST_UPDATE")
self:RegisterEvent("BN_FRIEND_ACCOUNT_ONLINE")
self:RegisterEvent("BN_FRIEND_ACCOUNT_OFFLINE")

-- OnEvent

local FriendsOnline = 0
for i = 1, GetNumFriends() do
	if select(5, GetFriendInfo(i)) then FriendsOnline = FriendsOnline + 1 end
end

local BNFriendsOnline = 0
for j = 1, BNGetNumFriends() do
	if select(7, BNGetFriendInfo(j)) then BNFriendsOnline = BNFriendsOnline + 1 end
end

local FriendString = string.format("%d/%d", FriendsOnline, BNFriendsOnline)
self.text:SetText(FriendString)
