Here's a simple skill explorer. It would probably be better if it was set up to skip IDs that are not skills but it is a quick and dirty solution. You can either copy and paste the code into the debug window from any of my plugins or you can create a lua file from it and add it to your own plugin.

import "Turbine.UI";
import "Turbine.UI.Lotro";
skillWindow=Turbine.UI.Lotro.Window()
skillWindow.cols=math.floor((Turbine.UI.Display:GetWidth()-10)/100)
skillWindow.rows=math.floor((Turbine.UI.Display:GetHeight()-105)/62)
skillWindow:SetSize(Turbine.UI.Display:GetWidth(),Turbine.UI.Display:GetHeight())
skillWindow:SetText("Skill Explorer")
skillWindow.StartCaption=Turbine.UI.Label()
skillWindow.StartCaption:SetParent(skillWindow)
skillWindow.StartCaption:SetText("Start:")
skillWindow.StartCaption:SetPosition(10,45)
skillWindow.StartCaption:SetSize(50,20)
skillWindow.Start=Turbine.UI.Lotro.TextBox()
skillWindow.Start:SetParent(skillWindow)
skillWindow.Start:SetPosition(65,45)
skillWindow.Start:SetSize(100,20)
skillWindow.Start:SetFont(Turbine.UI.Lotro.Font.Verdana16)
skillWindow.Prev=Turbine.UI.Lotro.Button()
skillWindow.Prev:SetParent(skillWindow)
skillWindow.Prev:SetSize(100,20)
skillWindow.Prev:SetPosition(170,45)
skillWindow.Prev:SetText("Previous")
skillWindow.Prev.Click=function()
    local start=tonumber(skillWindow.Start:GetText())
    if start==nil then start=0 end
    start=start-skillWindow.rows*skillWindow.cols
    if start<0 then start=0 end
    skillWindow.Start:SetText(string.format("0x%x",start))
    skillWindow.refresh()
end
skillWindow.Show=Turbine.UI.Lotro.Button()
skillWindow.Show:SetParent(skillWindow)
skillWindow.Show:SetSize(100,20)
skillWindow.Show:SetPosition(275,45)
skillWindow.Show:SetText("Refresh")
skillWindow.Show.Click=function()
    skillWindow.refresh()
end
skillWindow.Next=Turbine.UI.Lotro.Button()
skillWindow.Next:SetParent(skillWindow)
skillWindow.Next:SetSize(100,20)
skillWindow.Next:SetPosition(380,45)
skillWindow.Next:SetText("Next")
skillWindow.Next.Click=function()
    local start=tonumber(skillWindow.Start:GetText())
    if start==nil then start=0 end
    start=start+skillWindow.rows*skillWindow.cols
    skillWindow.Start:SetText(string.format("0x%x",start))
    skillWindow.refresh()
end
skillWindow:SetVisible(true)
skillWindow.QS={}
for row=1,skillWindow.rows do
    skillWindow.QS[row]={}
    for col=1,skillWindow.cols do
        skillWindow.QS[row][col]=Turbine.UI.Lotro.Quickslot()
        local qs=skillWindow.QS[row][col]
        qs:SetParent(skillWindow)
        qs:SetSize(34,34)
        qs:SetPosition(col*100-32, row*62+23)
        qs.label=Turbine.UI.Label()
        qs.label:SetParent(skillWindow)
        qs.label:SetSize(100,20)
        qs.label:SetPosition(col*100-32, row*62+57)
    end
end
skillWindow.refresh=function()
    local start=tonumber(skillWindow.Start:GetText())
    if start==nil then start=0 end
    
    for row=1,skillWindow.rows do
        for col=1,skillWindow.cols do
            local qs=skillWindow.QS[row][col]
            local sc=Turbine.UI.Lotro.Shortcut();
            sc:SetType(Turbine.UI.Lotro.ShortcutType.Skill)
            local val=string.format("0x%x",start+(row-1)*skillWindow.cols+col-1)
            sc:SetData(val)
            local success, result=pcall(Turbine.UI.Lotro.Quickslot.SetShortcut,qs,sc)
            qs:SetVisible(success)
            qs.label:SetText(val)
        end
    end
end
skillWindow.Start:SetText("0x70033832")

just set the "start" value to the highest travel skill ID that is known to you and start scanning. you should be able to find the missing skill IDs fairly easily (you will have to hover over the skills to check the tooltips to see if they are musters or travels).
